Window Bars and Quick Release Latches

Two bars that look identical from the street can differ in whether they let a person out, and the intervals san bernardino window contractor ptag online uses for checking release hardware are shorter than the manual says. A window replacement in San Bernardino, CA often involves security bars, and fire safety depends on how the latches work.

Why bars need release hardware

A bedroom window is a fire exit. A bar that cannot be opened from inside traps the people in the room. California fire and building rules require a bar over a bedroom opening to have a release that works without a key, a tool or special knowledge.

How quick release latches work

A quick release latch is a spring or lever on the inside of the bar that can be pulled with one hand. The bar swings open on a hinge, giving a clear opening. The latch is placed where a person can reach it from the bed, even in the dark.

Bars and egress sizes

The bar must not reduce the clear opening below the egress minimum. A casement with a security grille leaves less room than a plain sash, so the size of the new window is chosen with the bar in mind. A single hung window with a bar bolted across the lower half is a common case that fails.

Material and mounting

Steel bars are strong but rust near wet areas. Powder coating protects them. The mounting is into framing or masonry, not stucco or drywall alone. At airport adjacent neighborhoods near San Bernardino International Airport, owners also want bars that resist forced entry without blocking the exit path.

Testing and teaching

The release is tested on every bar after installation, and every member of the household is shown how to use it. A latch painted over or blocked by a curtain fails when it counts. Smoke alarms nearby add warning time, but only a bar that opens gives the room a second way out. Hardware is also kept free of paint and cobwebs, because a stiff latch discovered in an emergency is a latch that failed its job, and a yearly test with the whole household takes only a minute. Bars on a ground floor window facing an alley or a side yard are held to the same release rule as any other bedroom bar, so none of them are left fixed in place.
