Window Security Bars for Basement Windows: The Complete Protection Guide
Secure your basement windows with the right window security bars. Expert guide for US homeowners and renters: sizing, egress rules, DIY install, and top products.
More than bars, SWB offers peace of mind. We understand security at a structural level to explain it to you at a home level. Basement windows are the single most exploited entry point in American homes — according to the FBI Uniform Crime Report, approximately 60% of residential burglaries occur through ground-floor or below-grade openings, and basement windows rank at the top of that list. Their low visibility from the street, frequent lack of reinforcement, and proximity to utility rooms and interior access doors make them an irresistible target for intruders. Installing window security bars for basement windows is one of the most cost-effective, proven defenses any homeowner or renter can deploy. This complete guide covers everything you need to know: common US basement window sizes, how to choose the right bar style, egress compliance requirements under the International Residential Code (IRC), and step-by-step DIY installation tips — so you can fortify your basement today without hiring a contractor or spending thousands of dollars.

Why Basement Windows Are the #1 Burglary Entry Point in American Homes
Most homeowners spend their security budget on front doors, smart locks, and alarm systems — completely overlooking the basement. That is exactly the vulnerability that experienced burglars exploit. According to the FBI’s Crime in the United States report, burglars consistently prefer entry points that offer concealment and speed. Basement windows deliver both. They sit below street level, often screened by bushes, stairwells, or window wells, giving an intruder 30 to 90 seconds of unobserved work time — more than enough to pop a weak latch or break single-pane glass. In cities like Chicago, Detroit, Philadelphia, and Memphis — all ranked among the highest property-crime metros in the USA — police departments have specifically cited unsecured basement windows in public safety advisories. The financial damage is equally alarming: the average burglary loss in the US is $2,800 (FBI UCR 2022), not counting the psychological toll. A single set of window security bars for basement windows, priced well under $100, eliminates this vulnerability permanently. The math is straightforward — steel bars cost less than 4% of the average burglary loss, making them among the highest-return security investments available to any American household.
The Concealment Factor: Why Burglars Target Below-Grade Windows
Unlike first-floor or bedroom windows that face the street or a neighbor’s line of sight, basement windows are naturally shielded. Window wells, landscaping shrubs, exterior staircases, and overhanging decks all create blind zones where an intruder can work without being spotted. A 2021 study by the University of North Carolina’s Department of Criminal Justice & Criminology, based on interviews with convicted burglars, found that lack of visibility from the street was the single most cited factor in choosing a target window or door. Basement windows — by their very design — almost always check that box. Reinforcing them with steel window security bars eliminates the opportunity before it begins, making a burglar move on to an easier, unprotected property.
Glass-Break vs. Bar Protection: Why Passive Steel Beats Electronic Alarms
Glass-break sensors and alarm systems respond after a break-in attempt has already begun. By the time the sensor triggers, an alert is sent, and a monitoring center calls the police, a skilled intruder has already gained access. Average police response time in major US cities ranges from 7 minutes (smaller suburbs) to over 20 minutes in densely populated urban zones (Police Executive Research Forum, 2022). Window security bars for basement windows, on the other hand, stop the attempt physically — before entry, before the alarm, before the call. Steel does not have a signal delay. There is no battery to die, no Wi-Fi connection to drop, and no subscription fee. Bars are passive, permanent, and fail-safe. Think of them as the last line of physical defense that no software vulnerability can bypass.
Renters and Landlords: Who Is Responsible for Basement Window Security?
In most US states, landlords are legally required to provide tenants with a safe and habitable dwelling, which courts have increasingly interpreted to include basic window security measures, especially in high-crime areas. However, enforcement varies widely by jurisdiction. In New York City, Local Law 57 mandates window guards in any rental unit where a child under 10 resides. Chicago’s Residential Landlord and Tenant Ordinance (RLTO) similarly imposes safety standards. For renters whose landlords have not acted, removable and adjustable window security bars — like the telescopic models offered by SWB — provide a legal, non-damaging solution that can be installed without drilling and removed when moving out. This protects the tenant without violating lease terms that prohibit permanent modifications to the property.
Understanding Common Basement Window Sizes in US Homes
One of the most practical challenges of buying window security bars for basement windows is matching the product to the actual window dimensions. Unlike standard double-hung windows, basement windows in American homes come in a much wider range of sizes depending on the decade of construction, geographic region, and whether the window was designed for egress compliance. Getting the sizing right before you purchase is essential — bars that are too narrow won’t anchor properly, and bars that are too wide won’t fit the frame. The good news is that the SWB Model A telescopic system is specifically designed to accommodate the most common US basement window width range without permanent installation, making it the practical choice for the vast majority of American homes.
Standard Basement Window Dimensions by Construction Era
Homes built before 1978 typically feature basement windows in the 14″×20″ to 18″×24″ range — small, single-pane utility windows with minimal framing depth. Homes constructed between 1980 and 2000 generally widened to 24″×30″ or 30″×24″ configurations as basement finishing became more common. Post-2000 construction, driven by IRC egress requirements for habitable basement rooms, often features windows as wide as 36″ and as tall as 24″ to meet minimum opening requirements. The SWB Model A telescopic bars fit widths of 22″ to 36″, covering the most common post-1980 range. For windows outside that range, the Model B wall-mount system provides a custom-anchored solution for both narrower older windows and oversized modern openings.
Measuring Your Basement Window for the Right Bar Fit
Accurate measurement is the single most important step before purchasing any window security bar system. Measure the inside width of the window frame — not the glass pane, but the full interior frame width from jamb to jamb. Do this in at least two spots (top and bottom) because many older basement frames are not perfectly square due to foundation settling. Record the narrowest measurement and use that as your fit target. Also measure the depth of the window sill to confirm there is enough depth for the bar’s mounting bracket or tension foot. For standard US basement windows, inside frame widths between 22″ and 36″ are ideal candidates for the SWB Model A telescopic system, which installs in 15 to 20 minutes without power tools.
Window Well Considerations for Below-Grade Installations
Many US basement windows sit inside a window well — a curved or rectangular excavation lined with corrugated metal or concrete that allows light and ventilation for below-grade openings. Window wells create a unique security challenge: they provide physical concealment for a burglar crouching at the window. When installing window security bars for basement windows with a window well, you have two layers of protection to consider: the bars on the window itself (interior or exterior mount) and optionally a window well cover or grate over the well opening. SWB window bars can be installed on the interior side of the frame — keeping them protected from weather and vandalism — while still providing the same steel-bar deterrent effect. Interior installation also simplifies the egress release mechanism, as described in a later section of this guide.
Types of Window Security Bars for Basement Windows: Which Style Is Right for You
Not all window bars are built or designed with basement windows in mind. The market offers several categories — telescopic bars, fixed wall-mount bars, egress-compliant quick-release bars, decorative grates, and exterior grilles — and each has a distinct role depending on whether the basement is finished or unfinished, rented or owned, and whether the window must serve as a fire escape route. Understanding the full spectrum of options for metal bars windows and related security hardware is critical before making a purchase decision. SWB offers three models specifically engineered to address the different basement scenarios encountered across American homes, from Chicago rental units to Houston single-family homes to ground-floor commercial spaces in Los Angeles.
Telescopic Adjustable Bars: Best for Renters and Quick Installs
The SWB Model A is a fully telescopic, adjustable steel bar system that expands to fit window widths from 22″ to 36″ — no drilling required for most installations. The tension-mount design uses the structural integrity of the window frame itself to anchor the bars securely, delivering the same resistance force as welded fixed bars without any permanent modification to the window or wall. This makes the Model A the ideal solution for apartment renters, tenants in lease-restricted units, landlords who need to install and remove bars between tenants, and homeowners who want a fast security upgrade without a contractor. At $90, it delivers professional-grade deterrence at roughly 6% of the cost of a professional bar installation ($600–$1,800 average across US metro areas). You can learn more about the full telescopic design at the SWB Model A product page.
Fixed Wall-Mount Bars: Maximum Security for Owned Properties
For homeowners who own their property and want permanent, maximum-resistance security for basement windows, the SWB Model B wall-mount system is the right choice. Built from heavy-gauge steel with a powder-coated black finish, Model B anchors directly into the window frame surround or the surrounding wall using lag screws rated for masonry and wood framing. The fixed installation eliminates any possibility of the bars being pried, levered, or torqued loose — a known attack vector against poorly installed tension-mount systems. Model B is the preferred option for ground-floor basement windows in high-crime neighborhoods, detached garages with interior basement access, and any basement that contains high-value items such as a workshop, server room, or home gym. Details on specifications and ordering are available at the SWB Model B product page.
Egress-Compliant Bars: Required for Finished Basements and Sleeping Areas
If your basement includes a bedroom, a guest room, or any habitable sleeping area, building codes in all 50 states under the International Residential Code (IRC) Section R310 require that at least one window in that space be designated as an emergency egress opening. Any window bars installed on an egress window must include a quick-release mechanism operable from the inside without keys or special knowledge. The SWB Model A/EXIT is a patented telescopic bar system that integrates a code-compliant egress release directly into the bar frame. It meets IBC, NFPA 101 Life Safety Code, and IRC Section R310 requirements — making it the legally safe choice for any finished basement sleeping area. At $92, it is the most critical investment any finished-basement homeowner in America can make.
Egress Window Compliance: Building Codes Every Basement Owner Must Know
This is the section of the guide that most homeowners skip — and it is the one that can cost them a life or a building code violation fine. The International Residential Code (IRC), adopted in full or modified form by all 50 US states, contains specific language governing emergency egress from below-grade rooms. Understanding these rules is not optional for anyone installing window security bars for basement windows in a finished, occupied basement. The penalty for non-compliance is not just a fine — it is the potential inability of an occupant to escape a basement fire, which the National Fire Protection Association (NFPA) identifies as one of the deadliest residential fire scenarios due to smoke concentration and limited ventilation in below-grade spaces.
IRC Section R310: What the Law Actually Requires
IRC Section R310 mandates that every sleeping room in a basement must have at least one operable emergency escape and rescue opening. That opening must meet a minimum net clear opening width of 20 inches, a minimum net clear opening height of 24 inches, and a minimum net clear opening area of 5.7 square feet (5.0 square feet at grade floor). The sill height cannot exceed 44 inches above the floor. Critically, the code states that any window bars, grilles, grates, or covers installed on egress windows must be releasable or removable from the inside without the use of a key, tool, or special knowledge, and without removing the window itself. This is precisely the specification that the SWB Model A/EXIT was patented to satisfy — reviewed in detail at the Model A/EXIT egress-compliant product page.
NFPA 101 Life Safety Code and Basement Window Bars
While the IRC governs new residential construction, the NFPA 101 Life Safety Code applies broadly to existing occupancies including rental properties and commercial buildings with basement habitable space. NFPA 101 Section 24.2.2 echoes the IRC egress requirements and adds language specific to security bars: they must not impede the minimum required clear opening, and any locking mechanism must be operable without tools in a single motion from the inside. Non-compliant window bars installed on egress basement windows can trigger NFPA 101 violations during fire marshal inspections — a significant liability for landlords and property managers in cities like New York, Los Angeles, Houston, and Chicago, where rental property inspections are routinely conducted. Installing SWB Model A/EXIT eliminates this liability entirely.
State and Local Variations: NYC, California, and Texas
While the IRC provides the national baseline, individual states and cities impose additional requirements. In New York City, the NYC Building Code (based on IBC 2014 with local amendments) requires quick-release mechanisms on all window guards in any rental unit below the 6th floor. California’s Title 24 building standards reinforce IRC egress requirements with specific AHJ (Authority Having Jurisdiction) inspection protocols for below-grade rooms. Texas follows the IRC with county-level adoption, but several large counties including Harris County (Houston) and Dallas County require permitted inspections for any finished basement sleeping area, including verification of egress window compliance. Always check with your local building department before installing fixed, non-releasable window bars on any basement window that serves or could serve as an emergency exit.
DIY Installation Guide: How to Install Basement Window Security Bars in Under 20 Minutes
One of the most persistent myths about window security bars for basement windows is that installation requires a professional welder, a locksmith, or at minimum a skilled handyman with specialized tools. That myth was true when the only option was permanently welded exterior cage-style bars. Today, the SWB telescopic system changes that equation entirely. The Model A can be installed by any homeowner or renter in 15 to 20 minutes using only the hardware included in the box — no power tools, no drilling, no mess. The following step-by-step process applies to the SWB Model A and Model A/EXIT for standard US basement window frames. For the Model B wall-mount system, refer to the detailed instructions at the SWB installation guide.
Step-by-Step: Installing SWB Model A Telescopic Bars on a Basement Window
Step 1 — Measure: Using a tape measure, record the inside frame width (jamb to jamb) at both the top and bottom of the window opening. Use the narrower of the two measurements. Step 2 — Set the bar length: Collapse the telescopic bar to approximately 1 inch shorter than your measured width. Step 3 — Position: Place the bar horizontally across the window opening at the desired height — typically one-third from the top for a single-bar configuration, or evenly spaced for a two-bar setup. Step 4 — Expand and tension: Slowly extend the telescopic mechanism until the rubber-tipped end caps make firm contact with both jambs. Step 5 — Verify tension: Attempt to move the bar horizontally — it should not shift. Apply upward and downward pressure — it should hold firm. Step 6 — For the Model A/EXIT, familiarize all household occupants with the quick-release lever location before considering installation complete. Full visual guidance is available at the SWB installation guide page.
Pro Tips for Basement Window Bar Installation
For basement windows with painted or uneven jamb surfaces, lightly sand the contact points before installing the bar to improve the grip of the rubber end caps. If your basement window sits inside a deep frame (more than 4 inches of depth), the bar can be positioned further back from the glass plane, reducing the lever-pry angle available to an intruder. For windows wider than 30 inches, consider using two horizontal bars spaced evenly — this reduces the maximum gap width between bars to under 5 inches, which meets the New York City Housing Maintenance Code standard for window guard spacing and provides child fall-prevention protection as well as burglar deterrence. Always test the installation by pushing outward firmly on the center of each bar before relying on it for security — a properly tensioned SWB bar will not deflect more than 0.25 inches under moderate hand pressure.
Tools Needed and Time Estimates for Each SWB Model
SWB Model A (Telescopic): No tools required. Installation time: 15–20 minutes per window. Hardware included in box. SWB Model A/EXIT (Egress-Compliant Telescopic): No tools required for standard installation; a Phillips screwdriver may be needed for optional secondary anchor bracket. Installation time: 20–25 minutes per window. SWB Model B (Wall-Mount): Requires a power drill with masonry or wood bits (depending on frame material), lag screws (included), and a level. Installation time: 30–45 minutes per window. For concrete block or poured-concrete basement window surrounds common in Midwest construction (Ohio, Michigan, Indiana), use the masonry anchor kit included with Model B and pre-drill at low speed to avoid cracking the mortar joint.
Choosing Between Interior and Exterior Basement Window Bar Installation
A common decision point for homeowners installing window security bars for basement windows is whether to mount the bars on the interior or the exterior of the window frame. Both approaches are valid, but each has distinct advantages and trade-offs related to weather exposure, aesthetics, accessibility, building code compliance, and resistance to forced entry. The choice often comes down to whether the homeowner prioritizes maximum external deterrence (exterior mount) or maximum egress convenience and weather resistance (interior mount). For renters, interior mount is almost always the preferred and lease-compliant option. This section breaks down both approaches with practical guidance for the most common US basement window configurations.
Interior Mount: The Renter-Friendly, Weather-Protected Option
Interior-mounted window security bars sit inside the window frame, protected from rain, ice, and UV degradation — all significant factors in climates like the Pacific Northwest, New England, or the Great Lakes region. For renters, interior mount is the lease-safe approach: bars are installed entirely within the dwelling, create no external modifications to the building facade, and can be removed in minutes when moving out. Interior bars also place the egress release mechanism (on the Model A/EXIT) exactly where it needs to be — immediately accessible from inside the room in an emergency. The primary trade-off is reduced visual deterrence from the outside; a potential intruder approaching a basement window from the exterior may not immediately see the bars until they are already at the window.
Exterior Mount: Maximum Deterrence and Structural Reinforcement
Exterior-mounted bars — typically fixed wall-mount systems like the SWB Model B — are visible to anyone approaching the property and function as the most powerful visual deterrent available. Criminological research consistently shows that visible security hardware, including exterior window bars, reduces the likelihood of an attempted break-in because burglars pre-screen targets based on perceived effort and risk (University of North Carolina Department of Criminal Justice, 2021). Exterior mount also allows the bars to leverage the exterior wall structure for anchoring, typically providing higher pull-out resistance than tension-mount interior systems. The trade-off is permanent installation (not renter-appropriate), exposure to weather requiring corrosion-resistant coatings, and in some jurisdictions, exterior building modification permits.
HOA and Local Code Considerations for Exterior Bar Installation
Homeowners in communities governed by a Homeowners Association (HOA) must review their CC&Rs (Covenants, Conditions & Restrictions) before installing exterior window bars. Many HOAs in Sunbelt states like Arizona, Florida, and Nevada have architectural review requirements that may restrict visible exterior security hardware. In some historic districts — common in cities like Savannah, Philadelphia, and New Orleans — exterior bar installation may require approval from the local historic preservation board. Interior bar installation avoids both of these regulatory hurdles entirely while still delivering equivalent security performance for the vast majority of residential basement windows. When in doubt, install interior and consult your HOA or local building department for exterior modification guidance.
Product Comparison: SWB Window Security Bars vs. Competitors for Basement Windows
The US market for window security bars includes a range of products from national manufacturers, regional fabricators, and direct-to-consumer brands. Understanding how SWB compares to the most commonly available alternatives — including Mr. Goodbar (Pinpont Manufacturing), Grisham (Master Halco), Unique Home Designs, and Prime-Line Products — is essential for making an informed purchase. This comparison focuses specifically on performance characteristics relevant to basement window applications: adjustability for non-standard frame sizes, egress compliance options, installation difficulty, price, and availability across the USA. For a broader review of metal bars for windows, window grates, door grilles, safety grills, and the full range of physical security hardware for residential and commercial applications, refer to our comprehensive guide on metal bars for windows and related security hardware.
SWB vs. Mr. Goodbar: Drilling vs. No-Drilling
Mr. Goodbar by Pinpont Manufacturing is a widely distributed product available in hardware stores across the Southeast and Midwest. It requires drilling into the window frame or surrounding wall for installation — making it inappropriate for renters and adding 30 to 60 minutes to the installation time. For basement windows in rented properties or apartments, the no-drill SWB Model A delivers equivalent security without lease violations. Mr. Goodbar also does not offer a patented egress-compliant quick-release version, making it unsuitable by itself for finished basement sleeping areas under IRC R310. SWB Model A/EXIT addresses both limitations simultaneously.
SWB vs. Grisham (Master Halco): Adjustability for Non-Standard Sizes
Grisham produces fixed-dimension window bar panels in a limited set of standard sizes. For the non-standard window widths common in pre-1990 US basement construction — widths like 19″, 23″, or 31″ that fall between Grisham’s standard SKUs — buyers are forced to either order a custom panel (typically $200–$400 with 2–4 week lead time) or accept a poor fit. SWB’s telescopic mechanism eliminates this problem by providing stepless adjustment across the 22″–36″ range, covering the majority of post-1980 US basement window widths at a fixed price of $90. For homeowners who need a solution today rather than in a month, SWB ships via Amazon FBA with 1–2 day delivery to all 50 states.
Price vs. Professional Installation: The Real Cost of Doing Nothing
The average professional installation of welded exterior window bars in a US metropolitan area ranges from $600 to $1,800 per window, according to HomeAdvisor’s 2023 national cost data. For a typical US basement with two to four windows, that totals $1,200 to $7,200 — a cost that puts professional security out of reach for the majority of American renters and budget-conscious homeowners. SWB Model A at $90 per window delivers the same steel bar physical deterrence without the professional markup, without the scheduling delay, and without the permanent structural modification. For landlords managing multiple rental units — a key SWB customer segment — the savings across a portfolio of properties are substantial.
Basement Window Security for Special Scenarios: Renters, Parents, and Landlords
Window security bars for basement windows are not a one-size-fits-all product, and the specific needs of the end user matter significantly in choosing the right model and installation approach. Three user groups have particularly distinct requirements that are worth addressing in depth: apartment renters with basement-level units, parents concerned about child fall prevention, and landlords managing multi-unit residential properties. Each group faces a different combination of budget constraints, legal obligations, lease limitations, and safety priorities — and the SWB product line is specifically designed to serve all three.
Apartment Renters: Protecting Your Basement Unit Without Violating Your Lease
An estimated 44.1 million Americans rent their homes (US Census Bureau, 2023), and a significant subset of those renters live in below-grade or garden-level units — especially in dense urban markets like New York City, Chicago, Boston, and San Francisco. Basement and garden-level units are disproportionately targeted in burglaries precisely because renters in those units rarely install security hardware, either because they don’t know they can or because they fear lease violations. SWB Model A’s no-drill, tension-mount design is the legal and practical solution: it installs without any permanent modification, leaves zero damage to the window frame, and removes completely in under 5 minutes when you move out. Renters should document the installation with photos before and after to confirm no damage to the landlord’s property.
Parents: Window Bars as Child Fall-Prevention Safety Devices
In addition to burglar deterrence, window security bars for basement windows serve a critical child safety function. The Consumer Product Safety Commission (CPSC) reports that window falls send approximately 5,100 children under 12 to US emergency rooms every year. Basement windows, while typically too small for an adult egress, can still present fall hazards for toddlers and small children in finished basement playrooms or daycare spaces. When bars are installed with a maximum 4-inch gap between each bar — the standard used by New York City’s Local Law 57 for window guard spacing — they prevent a child’s head or body from passing through. For parents using their finished basement as a play area or guest room, the SWB Model A provides dual-function protection: burglar deterrence and child fall prevention in one steel system.
Landlords and Property Managers: Scalable Security Across Multiple Units
For landlords managing portfolios of rental properties — from duplexes in Houston to apartment buildings in Atlanta to multi-family complexes in Detroit — the ability to quickly install and remove window bars between tenants is a significant operational advantage. Traditional welded bars require a metalworker and a permit to remove; SWB Model A removes in minutes with no tools. This means turnover costs are dramatically reduced, security can be maintained during vacant periods (often the highest-risk time for a property), and bars can be reused across units as tenants move in and out. At $90 per window, outfitting a 10-unit building’s basement windows costs less than a single professional welded bar installation for one window. Volume purchasing information is available through the SWB contact page.
🏆 Conclusion
Basement windows are the most overlooked vulnerability in American home security — and the easiest one to fix. Whether you are a renter in a Chicago garden-level apartment, a homeowner in Houston concerned about ground-floor access, a parent childproofing a finished basement playroom in Atlanta, or a landlord managing multiple units in Philadelphia, the solution is the same: properly installed window security bars for basement windows deliver immediate, steel-strong protection at a fraction of the cost of professional installation. SWB’s three-model lineup — the telescopic Model A for renters and quick installs, the fixed wall-mount Model B for permanent maximum security, and the patented Model A/EXIT for egress-compliant finished basement sleeping areas — covers every basement window scenario encountered across American homes. Available on Amazon with fast nationwide shipping, SWB bars are in stock now and ready to ship to all 50 states. Do not wait for a break-in to discover your basement is the weak link. Install SWB window security bars today and eliminate the most exploited entry point in residential America before a burglar finds it first.

Yes. The SWB Model A telescopic window bar system uses a tension-mount mechanism that presses against the interior jambs of the window frame, anchoring the bar without any screws, bolts, or drilling required for most standard US basement window installations. The bar expands to fill the frame width from 22 to 36 inches, and rubber-tipped end caps grip the window jambs securely. This makes Model A the ideal solution for renters, tenants with lease restrictions, and anyone who wants a fast, damage-free installation that can be removed just as quickly when no longer needed.
Window security bars are legal to install on basement windows throughout the United States. However, if a basement window serves as an emergency egress opening — meaning it is in a sleeping room or habitable space that relies on that window for fire escape — the bars must include a quick-release mechanism operable from the inside without tools, keys, or special knowledge. This is required under IRC Section R310 and NFPA 101 Life Safety Code. The SWB Model A/EXIT is specifically engineered and patented to meet this requirement. Always check with your local building department for any jurisdiction-specific rules, especially in New York City, California, and Texas, which have additional local amendments.
The SWB Model A and Model A/EXIT telescopic systems fit basement window frame widths between 22 and 36 inches — covering the most common post-1980 US basement window sizes. This range includes standard configurations such as 24×20, 24×30, 30×24, and 36×24 inches found in homes across all US regions. For basement windows narrower than 22 inches (common in pre-1970 homes in the Northeast and Midwest) or wider than 36 inches, the SWB Model B wall-mount system is the recommended solution, as it can be configured to fit non-standard frame dimensions with proper anchoring hardware.
Yes, when properly installed with bars spaced no more than 4 inches apart, window security bars also function as effective child fall-prevention devices. The Consumer Product Safety Commission (CPSC) estimates that window falls injure approximately 5,100 children under 12 in the US every year. New York City’s Local Law 57 mandates window guards with a maximum 4-inch bar spacing in rental units where children under 10 reside — precisely to prevent fall-through incidents. SWB bars installed with correct spacing provide this dual protection: burglar deterrence and child safety in a single steel system. Note that egress-compliant windows with quick-release mechanisms (Model A/EXIT) should be reviewed carefully in child-occupied rooms.
Use the SWB Model A if you are a renter, need no-drill installation, or want bars you can remove when moving out. Use the SWB Model B if you own your home, want permanent maximum-security installation, or have basement windows in a high-crime area where visible exterior deterrence is the priority. Use the SWB Model A/EXIT if your basement includes a sleeping room or guest bedroom — this model’s patented quick-release mechanism ensures code compliance with IRC Section R310 and NFPA 101, protecting both your family’s safety and your liability as a homeowner or landlord. If your basement has both egress windows and non-egress utility windows, you can mix models: Model A/EXIT on the egress window and Model A or B on the remaining windows.
Yes, exterior installation of window security bars is possible and provides the strongest visual deterrence. The SWB Model B wall-mount system is engineered for exterior installation, anchoring directly into the masonry, wood framing, or window surround of the exterior wall. However, exterior installation creates a permanent modification to your property — making it unsuitable for renters — and may require HOA approval or local building permits in some jurisdictions. In cities like New York, San Francisco, and New Orleans with strict historic preservation or exterior alteration rules, always consult your local authority having jurisdiction (AHJ) before proceeding with exterior bar installation. Interior installation of SWB Model A or A/EXIT provides equivalent security performance without these regulatory considerations.
Installation time varies by model. The SWB Model A telescopic system can be installed in 15 to 20 minutes per window with no tools required — simply measure the frame width, set the bar length, position it across the opening, and extend the telescopic mechanism until it tensions firmly against both jambs. The Model A/EXIT takes 20 to 25 minutes per window for the same process, with an additional step to familiarize household occupants with the quick-release mechanism. The Model B wall-mount system requires a power drill and takes 30 to 45 minutes per window depending on the frame material (wood vs. masonry). Full installation instructions with visual guidance are available at the SWB installation guide page.
Yes. All three SWB window bar models — Model A, Model B, and Model A/EXIT — are available through SWB’s Amazon store (seller: SecurityWindowBars) with Amazon FBA fulfillment, providing 1-to-2 business day delivery to addresses in all 50 US states. This is a significant advantage over custom-fabricated bar systems or contractor-installed solutions that often involve 2 to 4 week lead times. For homeowners who need security immediately after a break-in attempt, a neighborhood security incident, or a new lease in a ground-floor unit, Amazon availability means protection can be in place within 48 hours of ordering.
