Window Air Conditioner
Security Bars

Your AC unit is worth hundreds. Your peace of mind is priceless. Don't let a loose window unit be the reason you get robbed.

Secure Your Unit Now

The "Lift & Slide" Threat

Most window AC units are held in place by gravity and a closed window sash. A thief knows this. By simply prying the window up (lifting) or shoving the unit sideways (sliding), they can bypass the unit entirely or steal it outright.

Window air conditioner security bars are the definitive solution. They create a steel cage or brace that mechanically fastens the unit to the building's structure, not just the window frame.

🏗️

Structural Anchor

Bolts directly into the exterior masonry or siding, making the AC unit a permanent part of the wall.

🛑

Total Immobilization

Prevents vertical lifting and horizontal sliding. The unit cannot move without specialized tools.

Anti-Theft

Copper thieves target AC units for scrap metal. A steel security bar makes your unit too much trouble to steal.

Choose Your Protection Level

Not all security measures are created equal. Select the right hardware for your risk profile.

Hardware Type	Security Level	Best Application
Sash Lock (Interior)	Low / Medium	Preventing window opening from outside.
Support Bracket	Medium	Preventing the unit from falling (Safety).
Full Security Cage	High / Maximum	Preventing theft and forced entry.
Steel Flat Bar	High	Budget-friendly anti-lift solution.

Installation: Do It Right

Installing window air conditioner security bars is a precision job. A loose bar is just decoration.

1. Find the Studs: Never screw a security bar into vinyl siding alone. You must hit the wood stud or use masonry anchors for brick.
2. No Wiggle Room: The bar should fit tightly against the unit. Use rubber shims if necessary to eliminate gaps that a crowbar could exploit.
3. Tamper-Proof Screws: Use "One-Way" screws. If a thief can unscrew your security bar with a Phillips screwdriver, it's not secure.
