The Endura Flap Thermo Sash 3e is designed to fit snugly into the track of most windows, with sizes available for windows ranging from 22" to 43" in width and at least 1" thick track.

Crafted with a heavy extruded aluminum frame, the Thermo Sash 3e is available in white and dark bronze, blending seamlessly with your existing window. 

The heart of the Thermo Sash 3e is the flexible polyolefin polymer flap, designed to remain functional in temperatures as low as -40°F. Lined with magnets along the edges, the flap offers superior sealing, remaining shut during heavy winds and extreme weather conditions. Additional magnets can be added to increase weather protection, or you can remove the magnets entirely to make the flap easier for timid cats to use. 

For added security and insulation, a locking cover and weather stripping are included with the Thermo Sash 3e. The product also comes with a 90-day return policy and a lifetime warranty, giving you peace of mind in your investment.
