Product Details
Over time, daily use and exposure to the elements can affect how a flap performs. A replacement flap restores the original movement, seal, and closure your Endura Flap system was designed to deliver, helping maintain a more consistent barrier between indoors and out.
Built for Everyday Use
Each flap is formed from a flexible polyolefin-based polymer selected for durability and resilience. It remains responsive across temperature changes rather than becoming stiff, allowing pets to move through comfortably while still supporting proper closure after each use.
Magnets work in combination with the flap to guide it back into position, helping maintain a more reliable seal against wind and airflow. Replacing the flap helps restore that alignment and overall performance.
Complete Kit for a Clean Refresh
Each kit includes the core components needed to return the flap to proper working condition, including pivot washers and a magnet set. Hole plugs are also included to match both original square corner frames and updated 45 degree corner frames for a consistent finished look.
Thermo Panels, Thermo Sashes, and new Pet Door Guys in-glass installations do not require hole plugs.
Wall mount pet doors with original square corner joints require threaded wall studs.
Straightforward Replacement
Full instructions are available for each Endura Flap configuration, guiding a clean replacement process and helping ensure proper alignment once installed.
