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.

- 1 Replacement Flap
- 3 Retainer Rings
- 8 Hole Plugs*
Tools
- Magnetic Phillips head #2 screwdriver
- Flat head screwdriver
- Drill
*Replacement flaps come with two sets of hole plugs, but you will only need to use one on your flap. For your door, use the set of 8 large hole plugs and discard the set of 4 smaller hole plugs.
Step 1 Remove the Hole Plugs
- First remove the Endura Flap from the door or wall.
- To do this, you will need to remove the hole plugs. Don't worry, we sent you some extra ones!
- You can drill a hole in each plug and wiggle the plug out with a screwdriver to pull them off.
Step 2 Unscrew the Frame
- Use the Phillips head screwdriver to remove the screws that were under the hole plugs from the frame then remove the entire flap assembly from the door or wall.
- Carefully bend the tabs holding the tunnel together upwards until horizontal, then remove the long side pieces of the tunnel by sliding them off of the flattened tabs.
- You can use the flathead screwdriver to get it started. Careful! The tabs may snap off if bent too much.
Step 3 Remove Retainer Ring
- Look for a metal rod at the top of the flap frame—remove one of the circular metal retaining rings by forcing it off with a flathead screwdriver.
Step 4 Remove the Rod
- Push the metal rod through the flap frame until it comes out on the other side.
- Pull the rod out and remove the flap.
Step 5 Expand the Bellows
- Position the new flap in place in the frame and make sure the magnets are attracting correctly. If they are not, try flipping the flap around (switching the interior and exterior faces).
- Sometimes the bellows (accordion-like sides of the flap) contract during shipping and prevent the magnets from attracting. To fix this, remove the pivot washers from the top corners of the flap and use a blow dryer to lightly heat the bellows and stretch them back out.
Step 6 Check the Magnets
- Before installing your new flap you should check to make sure that the magnets in the flap and the frame are attracting correctly.
- If they seem to be repelling, you probably need to flip the flap around so they work properly.
Step 7 Position the New Flap
- Guide the metal rod back through the flap and frame.
Step 8 Install Retainer Ring
- Push a new retainer ring on by holding the other side of the rod in place while pushing the ring on with your fingers.
Step 9 Re-Install the Pet Door
- Reinstall the flap assembly into the door, wall, or panel. Line the holes up so you can see light through them, then screw them into place.
- Install the new hole plugs using a rubber mallet or another non-metal tool such as a hammer and wood.

I love the replacement endurance flap but it’s very hard to take the old flap off and install the replacement flap that is in an exterior brick wall. You have to take the entire dog door out of the wall in order to put the new flap on.
United StatesGood flap
Worked like a charm. Dogs love it especially the puppy as this one taste better than the last one.
United StatesOnly one complaint.
I like that these have been redesigned so that there are screws holding the bottom piece on the flap. Here’s where there’s a problem, though: adding magnets. My son had to break the ends off of the magnets that we added to make it so our cats can’t open the flaps to get out. This was the only way we could put the screws back in to hold the bottom of the flaps together.
United StatesFit perfectly to the door we bought over 10 years ago, 100% best pet purchase ever
United StatesIt all looked so easy until we started to replace it. My dog door is like 10 years old with two big dogs and at one time three running through it like crazy fools. A lot has changed since then. The instructions did not match what we had. We prevailed, but it was very difficult to replace it. The product is 5+ for sure. Even after 10 years the quality is hands down 5+ and the best dog door on the market. I almost rated the flaps 4 stars but believe I’ll easily get another 10 years with the replacements.
