Integrity’s Window Opening Control Device limits the window opening to 4 inches unless overridden in a two-step process.
Developed in response to increasing focus on child safety and fall prevention, Integrity’s Window Opening Control Device [1] limits the window opening to 4 inches unless overridden in a two-step process. The factory installed option meets the ASTM F2090-10 window fall prevention standard, and is designed so that the limiter resets automatically each time the window is closed.
