Window Opening Control Devices

Window screens are only intended to keep bugs out, not prevent a potential fall. To meet standards created to assist in the prevention of window falls in children under five years old, we offer a Window Opening Control Devices that limits window opening to less than 4" when the sash is opened. The device may be disengaged, allowing the window to open fully for cleaning or egress, and it automatically re-engages when the sash is fully closed again.

Check local building codes to ensure your windows operate within the standards needed for safety.
