Questions

Can I get this pet door with a clear flap?

The Endura Flap is only available with a translucent flap, but if you want a similar high quality, aluminum frame pet door that has a clear flap, we highly recommend the Liberty Pet Door for Walls.

Other brands of pet doors with plastic flaps always warp and thus let in air. How do these flaps hold up over time?

The Endura Flap is made with a special polymer called Polyolefin. It remains safe, soft and flexible in temperatures as low as -40°F. It does not yellow nor harden in the sun. The patented magnetic design ensures the door door seals well for years. In fact, the pet door and flap are backed by a Lifetime warranty.

Is the Endura Flap clear?

It is a little foggy, but it is see through.

Over time, even a high performance flap will show signs of wear from daily use and changing weather. A fresh replacement flap restores the original swing, seal, and magnetic closure that your Endura Flap system was built around, helping maintain consistent comfort inside your home.

Each flap is formed from a flexible polyolefin based polymer chosen for its durability, resilience, and ability to handle temperature shifts. The material is designed to stay responsive rather than stiff, so pets can move through easily while the magnets help guide the flap back into position.

Every kit includes the core components required to return the flap to proper working condition, including pivot washers and a magnet set. Hole plugs are provided to match either original square corner frames or updated 45 degree corner frames, ensuring a clean finish after installation. Thermo Panels, Thermo Sashes, and New Pet Door Guys in the Glass installations do not require hole plugs.

Wall mount pet doors with original square corner joints require Threaded Wall Studs

Don't let a worn flap keep your pets from enjoying their freedom. Choose our Endura Flap Replacement Flaps to rejuvenate your pet door and provide a reliable, weather-resistant access point for your furry friends.

Full instructions are available for each Endura Flap configuration to guide a straightforward replacement and help ensure proper alignment once installed.
