The Endura Flap Vinyl Panel is the most insulated pet door on the market, designed specifically for vinyl-framed sliding glass doors that have Channel-style tracks (will not work with monorail tracks). Unlike other options for a sliding glass door with a dog built-in (which generally has a metal frame), this door has a vinyl frame to match the original vinyl of your door and fit more comfortably in the track.
This semi-permanent, extreme-weather dog door has a spring-loaded design, which makes installation quick and easy. It safely secures the panel in place without making any permanent alterations, which is ideal for rentals and vacation homes. This insulated dog door for sliding glass doors is engineered to withstand -40°F and 50 mph winds.
The magnets that line the flap ensure the utmost energy efficiency and keep the flap sealed during rough weather for the most extreme weather pet door possible. The Endura vinyl pet door for sliding glass doors also features Dual pane, Low-E glass, which blocks harsh light without compromising the amount of natural light coming in. If your track height is under 74.75" tall, check out the Custom Endura Flap Severe Weather Vinyl Siding Glass Dog Door.
