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.

Choose Your Protection Level

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

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.
