"The Endura Flap Vinyl Panel is the most insulating cat door on the market, designed specifically for vinyl-framed sliding glass doors of any size. Unlike other metal frames common among sliding glass door panels, the vinyl frame fits more comfortably in the track and matches the original vinyl of your sliding glass door. This semi-permanent pet door has a spring-loaded design, which means that no tools are necessary for installation. It safely secures the panel in place without making any permanent alterations, which is ideal for rentals and vacation homes! Engineered to withstand -40 degree weather and 50 mph winds, the magnets that line the flap ensure the utmost energy efficiency and keep the flap sealed during rough weather. The vinyl panel also features dual-pane, Low-E glass, which blocks harsh light without compromising the amount of natural lights coming in.


The newest, most innovative feature of the Vinyl Panel is that it includes two locking catches on the exterior of the frame to permit your original sliding glass door to lock securely to the frame. With this feature, there’s no need to hassle any makeshift locking device— we understand the importance of security.
