Double-Hung Window Opening Control Device Kit

This kit includes a left-hand and right-hand latch assembly to install on both sides of the venting sash to limit the opening to less than four inches when the sash is first opened. Also includes an instructional guide, bumpers and installation fasteners. Release of the device allows the sash to be further opened for full sash ventilation and/or emergency escape and rescue. The opening control devices are automatically reset once the sash is returned to its fully closed position. The double-hung opening control devices meet requirements of ASTM F2090-08 and ASTM F2090-10 for Window Fall Prevention Devices With Emergency Escape and (Egress) Release Mechanisms. This is a genuine Andersen product that works with their 200 Series Narroline, 400 Series Woodwright, 200 Series Tilt-Wash, and the 400 Series Tilt Wash double hung windows.
