Three building codes create the national standard for window bar fire safety. Because virtually all US states and jurisdictions have adopted one or more of these codes, their requirements effectively apply everywhere in the country.

All three codes converge on the same requirement: bedroom window bars must release instantly from inside without tools. This is not a technicality — it is the difference between a fire-safe installation and one that could trap occupants.

The SWB Model A/EXIT features a proprietary one-touch release mechanism that is inside-only — meaning it cannot be operated from outside the window. From inside the room, a single upward motion releases the bar, which falls free of the window channel and allows the window to be opened to full egress width within 3 seconds.

The mechanism is deliberately simple: no levers to find in the dark, no multi-step process, no strength requirement. In testing with occupants ranging from children (age 8) to elderly adults (age 78), all were able to operate the release successfully on first attempt after a single 30-second demonstration.

From outside, the bar is rigid and tamper-resistant. The release is inaccessible without breaking through the window — at which point the bar is already functioning as intended by preventing easy entry.

Code compliance alone is not enough. NFPA research on residential fire fatalities consistently identifies delayed egress — not structural barriers — as the leading cause of fire deaths in homes. The best quick-release bar in the world is only effective if occupants know how to use it under stress, in the dark, and possibly in the presence of smoke.

SWB recommends a monthly household fire drill that includes operating the Model A/EXIT release on every bedroom window. The drill should take less than 5 minutes and should include every member of the household, including children. Make the motion instinctive — lift the bar, release, open window, clear the sill.
