Burglar Bars for Windows Inside Apartments: The Complete Renter’s Security Guide
Discover how burglar bars for windows inside apartments work, renter rights by state, landlord rules, and no-drill options for NYC, Chicago & LA renters.
Security Window Bars (SWB), the #1 authority in residential perimeter protection in the USA, brings you the most critical advice to keep your home safe. If you rent an apartment, the threat to your security is very real: according to the FBI’s Uniform Crime Report, approximately 6.7 million home burglaries occur in the United States every year, and roughly 60% of those break-ins happen through ground-floor windows and doors. For the 44.1 million apartment renters counted in the 2023 U.S. Census, that statistic is more than an abstract number — it’s a daily reality. Installing burglar bars for windows inside an apartment is one of the most effective deterrents available, yet millions of renters assume it’s off-limits because they fear violating their lease or damaging the property. This comprehensive guide breaks down exactly how interior burglar bars work in a rental setting, what your landlord is legally responsible for, how renter rights differ across major states and cities like New York City, Chicago, and Los Angeles, and which modern no-drill, telescopic systems let you protect your home without risking your security deposit.
Ground-floor apartments are statistically the most burglarized residential units in the country. Unlike a unit on the fifth floor that requires elevator access…
Why Apartment Renters Need Burglar Bars for Windows Inside Their Units
Many renters underestimate how exposed their apartments truly are. Ground-floor and garden-level units sit at the highest risk, but second-floor units accessible via fire escapes, rear alleys, or low-hanging tree branches are nearly as vulnerable. The reality is that a burglar choosing between two apartments will almost always skip the one with visible window security and target the one with unprotected glass. That visual deterrence effect is precisely why burglar bars for windows inside an apartment are so powerful — the reinforcement is clearly visible from outside, signaling to would-be intruders that entry will be loud, slow, and difficult. Beyond deterrence, interior installation keeps the bars protected from weather corrosion and from being tampered with from the outside using bolt cutters or pry bars. According to a study cited by the National Institute of Justice, most residential burglars are opportunistic — they avoid homes that require more than 60 seconds of forced entry. Steel window bars dramatically increase that time threshold. For renters in cities like Chicago, where property crime rates in certain neighborhoods consistently exceed national averages, or in parts of Los Angeles where apartment complexes on ground-level streets face regular break-in attempts, adding interior window bars is not paranoia — it is rational, evidence-based home protection. The question is not whether you need them, but how to install them without losing your security deposit.
The Ground-Floor Apartment Risk Factor
Ground-floor apartments are statistically the most burglarized residential units in the country. Unlike a unit on the fifth floor that requires elevator access or stairwell navigation, a ground-floor window represents a direct, low-visibility entry point that can be forced in seconds. Burglars can test window locks from a public sidewalk without arousing suspicion. In densely populated urban areas — think the South Side of Chicago, parts of the Bronx in New York City, or East LA — this threat is compounded by higher ambient crime rates and less reliable street lighting in alleyways. According to the Bureau of Justice Statistics, renters are approximately 85% more likely to be victims of property crime than homeowners, partly because rental properties receive less consistent security investment from landlords. Interior burglar bars installed on ground-floor windows create a hard barrier between an opportunistic intruder and your belongings — and your family’s safety.
Fire Escape and Accessible Upper-Floor Windows
It would be a mistake to assume that living above the first floor automatically protects you. In New York City alone, there are millions of apartments with fire escape access visible and reachable from street level. A window that opens directly onto a fire escape landing is functionally equivalent to a ground-floor window from a security standpoint. Intruders who access fire escapes — whether from adjacent buildings, from rooftop access, or by climbing external ladders — face the same unobstructed window that a ground-floor apartment offers. The addition of interior window security bars on fire-escape-facing windows closes this gap. Critically, if you install bars on a fire-escape window, the bars must have a quick-release egress mechanism to remain code-compliant — a requirement we will cover in full detail in later sections of this guide.
The Renter’s Psychological Security Benefit
Security is not only physical. Numerous sleep studies and criminological surveys have documented the anxiety that renters in high-crime neighborhoods experience on a nightly basis, particularly those who are single occupants, elderly residents, or parents with young children. Knowing that your windows are protected by solid steel bars — not just a flimsy latch or a secondary sash lock — produces measurable peace of mind. Renters who install interior burglar bars for their apartment windows consistently report sleeping better, feeling more comfortable leaving their units unattended, and feeling less vulnerable overall. This psychological benefit is a real, tangible return on a relatively modest investment that starts at under $100 for a quality telescopic system from Security Window Bars.
How Interior Burglar Bars Work: Installation Methods for Renters
The most common objection renters raise when considering burglar bars for windows inside their apartments is the installation question. Traditional window bars — the kind you see permanently welded to exterior masonry on commercial properties or older homes — require drilling anchor bolts into the window frame or surrounding wall. For a renter, that type of permanent installation typically violates lease agreements and can result in charges against the security deposit at move-out. However, the modern security hardware market has largely solved this problem with telescopic and pressure-fit systems designed explicitly for renters. These systems use the same physics as a tension rod: hardened steel bars extend to fit snugly within the window frame, locked in place by compression rather than by fasteners driven into the structure. The force required to dislodge a properly tensioned steel security bar is enormous — far beyond what a burglar attempting a quick, quiet break-in is willing to invest. SWB’s Model A Telescopic Window Bars, for example, adjust to fit windows from 22 inches to 36 inches wide, install in 15 to 20 minutes without a single drill hole, and can be fully removed in minutes when you move out, leaving zero trace on the window frame. This approach makes interior window security accessible to the 44 million renters who previously thought bars were simply not an option for them.
Telescopic (Pressure-Fit) Bar Systems: The Renter’s Best Option
A telescopic window security bar works by extending horizontally across the interior width of a window frame and applying outward pressure against both vertical jambs. The mechanism is similar in concept to a tension curtain rod but engineered from heavy-gauge steel and designed to resist lateral impact forces that a curtain rod could never withstand. SWB’s Model A Telescopic Window Bars ship directly via Amazon FBA, meaning they arrive at apartments across all 50 states within days. The matte black powder-coated finish looks intentional and modern rather than institutional, which matters to renters who want security without turning their apartment into a fortress aesthetic. Because no adhesives, screws, or anchors touch the building structure, these bars satisfy the no-permanent-alteration clauses found in virtually every standard US residential lease. For renters in Chicago, Houston, Atlanta, Philadelphia, or any high-crime urban market, these systems represent the most practical entry point into serious window security.
Wall-Mount Bars: When Your Landlord Approves Permanent Installation
In some rental situations, particularly long-term tenancies, landlords will agree in writing to allow permanent window security upgrades, especially if the installation increases the property’s security and value. In these cases, SWB’s Model B Wall-Mount Window Bars provide a step up in rigidity and permanence. Built from heavy-gauge steel with a powder-coated black finish, these bars are anchored directly into the window frame or surrounding wall studs, creating a fixed barrier with zero flex. If your landlord grants written permission for this type of installation, be sure to document the approval, keep a copy of the agreement, and photograph the installation upon completion. In NYC, Chicago, and LA, where some landlords proactively install window guards as a liability measure, a landlord-approved Model B installation may even be incorporated into the lease as a property improvement — which can protect you from any deposit deduction at move-out.
Egress-Compliant Bars: The Non-Negotiable Safety Upgrade
Any burglar bar installed on a bedroom window or sleeping area window in a US residential property — rental or owned — must comply with egress requirements under the International Building Code (IBC) and NFPA 101, the Life Safety Code. These codes require that sleeping area windows provide an unobstructed emergency escape opening of at least 20 inches wide by 24 inches tall. Standard fixed bars that cannot be released from the inside create a life-threatening trap in the event of a fire. SWB’s Model A/EXIT Egress-Compliant Window Bars address this directly with a patented quick-release mechanism that allows the bars to be opened from inside in seconds — without any tools — while remaining completely secure against outside forced entry. This model is the correct choice for any bedroom window, any window in a sleeping area, and any window that overlooks a fire escape route. No exceptions.
Landlord Responsibilities and Renter Rights: What the Law Says
One of the most misunderstood aspects of window security in rental housing is the legal division of responsibility between landlords and tenants. Many renters assume their landlord is required to provide window bars or security screens — and in some jurisdictions, they are correct. However, the specific requirements vary widely by state and municipality, and failing to understand your local rules can mean either missing out on security upgrades you’re legally entitled to demand or unknowingly violating your lease with unauthorized modifications. The foundation of landlord responsibility in the US is the Implied Warranty of Habitability — a legal doctrine recognized in virtually every state that requires landlords to maintain rental properties in a condition fit for safe and healthy human habitation. Courts in many states have interpreted this warranty to include basic security measures, though window bars specifically are only explicitly mandated in a small number of jurisdictions. Renters who want to install their own security measures — including burglar bars for windows inside their apartment — should always start by reading their lease carefully, then consulting the specific building codes and rental regulations for their city and state.
New York City: Local Law 57 and Mandatory Window Guards
New York City has some of the most specific window security legislation in the country. Under NYC Local Law 57 (Administrative Code Section 27-2043.1), landlords are required by law to install window guards in any apartment where a child under 10 years of age resides or is a regular visitor, upon written request from the tenant. Landlords must also provide all tenants with annual written notice of this right. Failure to install guards when required can result in significant fines for building owners. For renters in NYC who do not qualify under Local Law 57 but still want additional window security, telescopic interior bars require no landlord approval because they cause no structural modifications. However, any window facing a fire escape is particularly critical — and must use an egress-compliant bar system that allows emergency exit, per FDNY and NYC Building Code requirements.
Chicago: Residential Landlord and Tenant Ordinance
Chicago’s Residential Landlord and Tenant Ordinance (RLTO) is one of the strongest tenant protection frameworks in the Midwest. While it does not specifically mandate window bars, it does require landlords to maintain rental properties in compliance with the Chicago Building Code, which includes provisions for window security hardware in certain building classifications. Chicago renters in high-crime areas such as Austin, Englewood, or West Garfield Park may request security improvements in writing; if the landlord fails to respond or refuses unreasonably, tenants may have grounds to pursue remedies under the RLTO. For practical, immediate protection, a telescopic no-drill system is the fastest path forward for Chicago renters who cannot wait for landlord action.
Los Angeles and California Statewide Renter Protections
California’s Tenant Protection Act (AB 1482) and the Los Angeles Rent Stabilization Ordinance primarily address rent increases and eviction protections, but California law also grants tenants the right to request security improvements under the habitability doctrine. California Civil Code Section 1941 obligates landlords to provide rental units with deadbolts, locking windows, and — in some court interpretations — adequate security against foreseeable criminal intrusion. LA renters who have experienced prior break-ins or who live in buildings with a documented history of crime may have a stronger legal basis for demanding landlord-funded security upgrades. For self-help security without waiting for landlord action, California law generally permits tenants to install non-damaging security devices, making telescopic interior window bars the most legally safe option in the state.
Choosing the Right Burglar Bars for Your Apartment Window Type
Not all apartment windows are the same, and choosing the right interior security bar depends on your specific window configuration, size, and usage. The three most common residential window types found in US apartments are double-hung (vertical sliding sash), single-hung, and horizontal sliding windows. Each has slightly different considerations for bar placement and pressure-fit anchoring. Before purchasing any window security system, measure your window’s interior width carefully — measuring from the inside of the left jamb to the inside of the right jamb — at three points: the top, middle, and bottom of the window opening. Use the smallest measurement. For standard US apartment windows, which typically range from 24 inches to 36 inches wide, SWB’s telescopic systems are engineered to fit precisely within this range. Basement apartment windows present a unique challenge: they tend to be shorter in height and wider in proportion, which makes horizontal bar placement critical. The complete lineup of window security solutions from Security Window Bars — including telescopic, wall-mount, and egress-compliant models — covers the full spectrum of apartment window scenarios renters encounter across the country.
Standard Double-Hung Windows: The Most Common US Apartment Window
Double-hung windows — the kind where both the upper and lower sash slide vertically — are the predominant window type in US apartment buildings constructed before 1990 and remain widely used in new construction today. For interior bar installation on a double-hung window, the bar should be placed horizontally across the window opening, anchored against the vertical side jambs at a height that prevents the window from being opened far enough for a person to pass through. SWB’s Model A Telescopic Window Bars are specifically calibrated for this configuration, with adjustable length from 22 to 36 inches and pressure-fit end caps that grip the painted or bare wood jamb without scratching or marking. The installation manual available at the SWB website walks renters through the process step by step, typically taking under 20 minutes without any tools beyond a tape measure.
Sliding Windows and Basement Windows: Specific Considerations
Horizontal sliding windows — common in apartment buildings constructed in the 1970s and 1980s in cities like Houston, Dallas, and Phoenix — require a different bar orientation. For these windows, the security bar is placed vertically in the window track to prevent horizontal sliding, combined with a horizontal bar across the full frame opening for added reinforcement. Basement apartment windows present a compounded security challenge: they are typically at or below exterior grade level, meaning a burglar can work on the window in near-total concealment from street view. For basement windows specifically, the addition of a wall-mount system — where the landlord permits it — provides the strongest possible deterrent. Where only a no-drill system is permissible, layering a horizontal telescopic bar with a secondary sash lock provides meaningful reinforcement even without permanent anchors.
Bedroom Windows: Egress Compliance Is Not Optional
It bears repeating with full clarity: any burglar bar installed on a bedroom window in any US residential unit — whether owned or rented — must allow emergency egress from inside the room without tools or keys. The International Building Code (IBC) and the International Residential Code (IRC) both require emergency escape and rescue openings in sleeping rooms, with minimum dimensions of 20 inches wide by 24 inches tall and a maximum sill height of 44 inches from the floor. NFPA 101, the Life Safety Code, reinforces this requirement with specific language about bars, grilles, and screens on egress windows. SWB’s Model A/EXIT was engineered precisely to meet these standards, featuring a patented quick-release mechanism that satisfies IBC, NFPA 101, and OSHA requirements simultaneously. For a comprehensive look at how interior window security bars and egress compliance interact across different product categories, our full guide on window security bars and safety window bars covers every scenario in depth.
Installation Guide: Setting Up Interior Window Bars in Your Apartment Without Drilling
The installation process for a telescopic no-drill window security bar is deliberately straightforward — SWB designed these systems so that the average renter can complete the installation alone, without calling a contractor or locksmith, in under 20 minutes. However, doing the job correctly matters enormously for both security performance and lease compliance. A carelessly installed bar that shifts, rattles, or leaves marks on the window frame defeats both purposes. The following step-by-step overview reflects the process documented in detail in the SWB installation guide, which is available in full at the Security Window Bars website. Before you begin, gather your supplies: a measuring tape, a pencil for marking, and the bar itself. No drill, no screws, no adhesive, no tools beyond a tape measure are required for the Model A telescopic system.
Step-by-Step: Measuring and Fitting Your Telescopic Bar
Step one: Measure the interior width of your window opening at the point where you plan to place the bar — typically at the midpoint of the lower sash for maximum obstruction against entry. Write down the exact measurement. Step two: Adjust the telescopic bar to approximately half an inch shorter than your measured width. Step three: Position the bar horizontally across the interior of the window frame at your chosen height. Step four: Extend the telescopic mechanism until both end caps make firm contact with the window jambs on both sides. Step five: Apply tension until the bar is firmly locked in place — you should not be able to pull it free with moderate hand pressure. Step six: Test by pushing the center of the bar firmly toward the window; there should be no flex or movement. Step seven: Inspect the contact points to confirm no paint cracking, indentation, or marking on the jamb surface. If marking occurs, thin rubber or foam padding under the end caps resolves this without affecting security performance.
Common Installation Mistakes Renters Make and How to Avoid Them
The most frequent installation error is placing the bar too high in the window frame, leaving enough gap at the bottom for an intruder to reach through and manipulate the window latch. Place the bar at a height that reduces the maximum openable gap to under 6 inches — the minimum width recommended by most security experts to prevent unauthorized arm access. A second common error is insufficient tension: renters often feel reluctant to apply full extending force for fear of cracking the window jamb. Quality telescopic bars distribute that force across the full width of the end cap contact surface, meaning the pressure per square inch is low enough to be safe for all standard wood, vinyl, and painted window frames. A third mistake is ignoring secondary windows: securing only the most visible window while leaving the bathroom or kitchen window unprotected gives burglars an easy secondary entry point. Protect every accessible window consistently.
State-by-State Renter Rights: Can You Install Burglar Bars in Your Apartment?
The legal question of whether a renter can install burglar bars for windows inside their apartment without landlord permission — and whether doing so can result in lease termination or security deposit forfeiture — depends on the specific state and, in many cases, the specific lease language. Across the US, there is no single federal rule governing this question. Instead, the answer emerges from the intersection of state landlord-tenant law, local building codes, and individual lease terms. The general principle that applies in most states is this: renters may install non-damaging, reversible security devices without landlord permission, but permanent modifications — anything that involves drilling into walls, floors, or permanent structural elements — typically require written landlord consent. Below are key distinctions across the states and cities most relevant to this guide.
States With Strong Tenant Security Rights: California, New York, Illinois
California, New York, and Illinois are among the most tenant-protective states in the country. California Civil Code and court precedents support renters’ right to install non-damaging security devices, and state law explicitly allows tenants to install deadbolts and window locks without landlord permission in many circumstances (California Civil Code Section 1941.3). New York’s warranty of habitability is broadly interpreted by courts, and NYC Local Law 57 creates affirmative landlord obligations for window guards in buildings with young children. Illinois’s Chicago RLTO applies within Chicago city limits; outside Chicago, Illinois falls under the general landlord-tenant law framework, which is less tenant-protective but still recognizes habitability obligations. In all three states, telescopic no-drill bars are the safest legal path because they create zero permanent modification.
States With Weaker Tenant Protections: Texas, Florida, Georgia
Texas, Florida, and Georgia provide considerably less statutory tenant protection than California or New York. Texas Property Code requires landlords to install and repair certain security devices including window latches, but does not mandate window bars. Florida Statute 83.51 requires landlords to maintain functional window locks but similarly does not require bars or grilles. Georgia has limited statutory requirements for landlord security obligations. In these states, renters who want window bars have less legal leverage to demand them from their landlord but retain the practical option of installing non-damaging telescopic systems entirely at their own discretion. Houston, Dallas, Miami, and Atlanta renters in particular face elevated property crime rates in many neighborhoods, making self-installed telescopic bars a smart and legally uncontroversial choice.
The Lease Review Checklist: What to Look For Before Installing
Before purchasing and installing any window security product in your apartment, review your lease for these specific clauses: (1) Alterations and Modifications — look for language prohibiting alterations “of any kind” versus language that specifically prohibits “permanent” or “structural” modifications; telescopic no-drill bars should fall outside most reasonable interpretations of prohibited alterations; (2) Restoration Obligations — clauses requiring you to return the unit to its original condition at move-out are satisfied by telescopic bars because they leave no trace; (3) Landlord Approval Requirements — some leases require written approval even for non-damaging additions; if so, send a brief written request to your landlord before installing; (4) Fire Safety and Building Code Compliance — if your lease includes a general compliance with building codes clause, ensure that bedroom window bars are egress-compliant as described above. When in doubt, a 10-minute conversation with a local tenant rights organization or a tenants’ legal aid hotline can clarify your specific situation at no cost.
SWB Products Built for Apartment Living: No Drill, No Deposit Risk
Security Window Bars designed its entire residential product line with the renter in mind. The most common barrier between an apartment renter and proper window security has historically been the fear of lease penalties and security deposit deductions. SWB eliminates this barrier entirely with telescopic and egress-compliant systems that install without touching the building structure in any permanent way. Every SWB product ships via Amazon FBA with Prime-eligible delivery to all 50 states, meaning renters in Memphis, Detroit, Philadelphia, New York, Chicago, Los Angeles, and every city in between can receive a professional-grade window security system within days of ordering — no contractor visit required, no scheduling delays, no installation fees. At $90 to $92 per window, SWB bars cost a fraction of the $600 to $1,800 that a professional security bar installation typically runs, and they move with you when your lease ends.
Model A — Telescopic Window Bars: The Standard for Renter Security
The Model A Telescopic Window Bars are the flagship product for apartment renters across the USA. Adjustable from 22 to 36 inches — covering the overwhelming majority of standard US window sizes — they install without drilling in under 20 minutes and deliver the same visual and physical deterrence as welded permanent bars. The heavy-gauge steel construction resists prying, cutting, and impact. The matte black powder-coated finish is durable against moisture and resists rust, making it suitable for kitchen and bathroom windows as well as living spaces. At $90 per unit, a renter can secure three windows in a one-bedroom apartment for under $300 — compared to potentially thousands of dollars for professional installation and zero loss of security deposit at move-out.
Model A/EXIT — Egress-Compliant Bars: The Bedroom-Safe Choice
The Model A/EXIT Egress-Compliant Window Bars carry a patented quick-release mechanism that makes them the only choice for bedroom windows in any residential setting — rental or owned. At $92, they represent the safest possible investment for sleeping area window protection: full steel security against forced entry from outside, combined with immediate inside-release capability for emergency escape. This product is fully compliant with IBC, IRC, NFPA 101, and OSHA egress standards — critical for renters whose buildings may be subject to fire inspection or code compliance review. For renters in New York City, where FDNY fire safety inspections are common in multi-unit residential buildings, installing non-egress-compliant bars on any sleeping area window creates a legal and safety liability.
Ordering and Delivery: Amazon FBA Across All 50 States
All SWB products are available through the Security Window Bars Amazon store, fulfilled by Amazon FBA for fast, reliable delivery to all 50 states. Prime members can typically receive orders within one to two business days, making SWB the fastest path from “I need security” to “my windows are protected” in the industry.

In most US states, you can install non-damaging, reversible security devices — including telescopic no-drill window bars — without explicit landlord permission, because they create no permanent structural modification. However, if your lease contains a broad alterations clause requiring written approval for any additions, it is safest to send a brief written request to your landlord first. Telescopic pressure-fit bars like SWB’s Model A leave zero marks and can be fully removed at move-out, satisfying the restoration requirements found in virtually all standard US residential leases. Always check your specific lease language and, if in doubt, contact a local tenant rights organization for a definitive answer in your jurisdiction.
Fixed, non-opening burglar bars on bedroom or sleeping area windows do create a life-safety hazard by blocking emergency egress — and this is a serious, code-regulated concern. However, egress-compliant bars with a quick-release mechanism from inside the room are specifically engineered to solve this problem. SWB’s Model A/EXIT Egress-Compliant Window Bars meet IBC, NFPA 101, IRC, and OSHA standards and allow full emergency exit from inside without tools or keys. For any bedroom window or sleeping area window, the Model A/EXIT is the only code-compliant option. Fire-escape-facing windows also require egress-compliant bars per FDNY guidelines and local building codes in cities like New York and Chicago.
It depends heavily on your city and state. In New York City, Local Law 57 requires landlords to install window guards in apartments where children under 10 reside or regularly visit, upon written tenant request. In Chicago, the Residential Landlord and Tenant Ordinance requires landlords to maintain properties in compliance with the building code, which includes window security provisions. In California, landlords are required under Civil Code Section 1941 to provide habitable conditions, which courts have extended to include reasonable security measures. In states like Texas, Florida, and Georgia, landlord obligations are more limited. If your landlord is non-responsive to a written security improvement request, contact a local tenant rights hotline for guidance specific to your state.
No — provided you use telescopic no-drill window bars and install them correctly. Pressure-fit telescopic systems like SWB’s Model A make no contact with fasteners, anchors, or adhesives. They apply only outward tension against the window jambs, which causes no damage to paint, wood, vinyl, or metal window frames when properly padded end caps are used. At move-out, the bar is removed in seconds, leaving no trace. This is fundamentally different from drilling anchor bolts into the wall around a window frame, which would cause measurable damage. To be absolutely safe, photograph your windows before installation and after removal at move-out to document the unchanged condition of the frames.
Measure the interior width of your window opening — from the inside of the left jamb to the inside of the right jamb — at the mid-point of the opening. Standard US apartment windows typically range from 24 to 36 inches wide. SWB’s Model A and Model A/EXIT Telescopic Window Bars adjust from 22 inches to 36 inches, covering the vast majority of standard US residential window sizes. If your window is wider than 36 inches, consider using two bars positioned at different heights across the same window, or contact SWB directly for guidance on larger window configurations. For narrower basement windows, measure carefully — some egress windows in older construction can be as narrow as 18 to 20 inches and may require a different solution.
According to research cited by the National Institute of Justice, the overwhelming majority of residential burglars are opportunistic — they choose targets based on the path of least resistance and the lowest risk of being caught or delayed. Most avoid targets that will take longer than 60 seconds to breach. Steel window bars — even interior telescopic versions — dramatically increase the forced-entry time beyond that threshold, making the target unattractive relative to unprotected nearby units. Additionally, the visible presence of window bars from outside functions as a powerful psychological deterrent before any physical contact is made. In dense urban apartment environments, where multiple units are visible from a single vantage point, burglars consistently bypass secured windows in favor of unprotected ones.
Yes — and this is one of the most significant advantages of telescopic no-drill window bars over professionally installed permanent systems. Because SWB’s Model A and Model A/EXIT bars are fully adjustable and require no permanent anchoring, they can be removed from one apartment, transported, and reinstalled in a new apartment in a single afternoon. As long as the new windows fall within the 22-to-36-inch adjustable range, the same bars that protected your current unit will protect your next one. This portability makes the one-time purchase of quality telescopic window bars an ongoing, multi-use security investment rather than a single-property expense — particularly valuable for renters who move frequently or who plan to relocate within a few years.
In casual US usage, the terms are often used interchangeably, but technically they refer to slightly different products. Window bars typically refers to horizontal steel bars spanning the window opening, designed primarily to prevent unauthorized entry. Window guards is a broader term that includes grille-style products, vertical bar configurations, and — in the specific context of New York City’s Local Law 57 — window fall-prevention devices installed to stop young children from falling out of open windows. Both categories are served by the SWB product lineup. For entry deterrence in an apartment setting, interior window bars are the correct product. For child fall prevention, window guards (often a grille or multi-bar system covering the full window opening) are the appropriate solution and may be legally required by your landlord in certain jurisdictions.
