This pet door is all about the flap. This new door uses the Endura flap, which has been tested beyond 3,000,000 cycles without a failure!!! The key to its durability is that it swings on bushings at the top instead of flexing at the top like a typical soft vinyl flap, this pivot allows the door to swing without wear and tear. This new Endura flap is available in taller sizes than most other pet doors. The manufacturer refers to this as "aspect ratio". A high aspect ratio with a tall skinny flap makes it easier to fit multiple dogs, as the flap can be lower to the ground and yet still be tall enough for a larger dog at the same time, and is still not unnecessarily wide. Because of the full length magnets that go all the way down the sides and across the bottom of the flap, this door requires more force to open. We have customers with cats using the largest size, but if your pet is particularly skittish you may want to consider the alternatives and consider a Hale door as they are easier to open.


Endura Door Pet Door

There are 3 important sizes with respect to pet doors:

Flap Size is the most important, so it is listed on the main page. This is the size of the space that your pet will have to fit through.

Cutout Dimension refers to the size of the hole that needs to be cut in a wall to install the pet door.

Outside Dimension is the size of the outside of the frame, which can sometimes be important when installing a pet door in a limited space.

All sizes are given Width x Height.

Please read instructions thoroughly before beginning installation.

1. Tape the provided template to the door.

Figure 1: Leveling the template The top edge of the cut-out line should be 1-1/4 inch (or more) above the dog’s withers (shoulders) for the single flap door mount, and 2 inches for the double flap door mount. Be careful not to unduly reduce the strength of the door by cutting too close to the bottom of the door. Level the top edge of the cut-out line as shown
in Figure 1.

2. Mark the hole centers for the four holes and remove the template.

3. Drill the four 3/8 inch holes as shown

Figure 2: Drilling four 3/8” holes in Figure 2. Note: Drill bit needs to be long enough to go through the interior and exterior of the door. It should be both level and straight when making the holes to ensure the two frames will align properly.

4. Draw lines to connect the outsides of    

5. Cut along the line as shown in Figure 3. Note: Jigsaw needs to be level and straight when cutting the lines to ensure the two frames will align properly.

6. Install the weather-stripping into the groove on both frames with the start/end gap at the bottom.

7. If a single flap door mount, place the pet door trim frame on the outside of the doorand the flap frame on the inside and skip to Step 14.

8. If a double flap door mount, assemble the four-piece tunnel by first bending the screw tabs down as shown in Figure 4 in the top and bottom tunnel pieces (the two identical shorter pieces). Note: Only bend the tabs once, bending more than once may result in the tabs breaking off.

These images are representative. Appearance of your pet door may vary slightly depending on model.

Figure 5: Remove the four flap assembly screws

9. Remove the screws in the four corners of the flap frame assembly as shown in Figure 5.

10. Place the top piece on, with the bent tabs down and align the top piece so the holes in the tabs lines up with the screw holes in the flap frame and screw in as shown in Figure 6. Repeat for the bottom piece.

11. Slide in the tunnel side pieces as shown in Figure 7.

12. Bend the tabs down with your thumb or a screwdriver handle.

13. Place the flap frame with the tunnel attached on the inside and Figure 6: Align the top and bottom pieces and screw into place the other flap frame outside.

14. Select the 2-1/4 inch set of screws for 1-3/4 inch doors and the shorter set for 1-3/8 inch doors. Insert these into the pet door from the inside. For doors with a thickness of less than 1-3/8 inch, see special instructions. For doors between 1-3/4 inch and 2-1/4 inch with the double flap door mount,
use the 2-3/4 inch screws.

15. Start all four screws as shown in Figure 8, but do not tighten.

16. Before tightening down the screws, check that the pet door is level and adjust as needed.

17. Tighten the screws until the weather-stripping compresses and Figure 7: Push on the tunnel sides
the pet door touches the door. Do not over tighten.

18. Hammer the hole covers into the frame using the wooden end of a hammer (or similar non metal tool).

19. For double flap door mounts, apply silicone along the inside of the tunnel where it mates with the flap frames to seal your pet door from the elements. Failure to seal your pet door can lead to
severe water damage.

    Endura Pet Door for Doors

    Posted by Josh Kline on Sep 23rd 2021

    I wasn't exactly sure what I needed, so I started a chat with the support agent. After describing the size of my dog and the unique window/door setup, they made a recommendation. I am extremely happy with this door. You can tell it is quality built and should last a long, long time. My dog loves it too, which really is the most important part! Thank you!

    High quality door, quick shipment, easy install

    Posted by Clay on Sep 4th 2018

    Everything about this door install went well. I went with the 2 flap "large" version for my 55lb cattle dog mix, which might have been a little big, but it gives some extra room if my brother's GSD comes over. Overall, the instructions were good, the hardware was good, the materials were great, the seal is near perfect (I can still see a small air gap), and I'm pretty happy.

    Probably the best purchase ever made, other than our 39 Lb. Labradoodle Taylor. It,s a dream come true living in a condo with a large deck & not having to hike the dog down the elevator or stairs to do his business out & about in bad weather. The sound of "click click" is music to your ears 24/7. The youtube video is absolutely correct from ease of installation, to its long term reliability. This is a worthwhile investment for all members of the family. Enjoy KG

    Best dog door!

    Posted by Trey Jamison on Jul 26th 2016

    This door is amazing. They thought of everything when they designed it. It opens easily to the push at the bottom, but stays amazingly sealed through anything else. The two flap design is certainly more energy efficient than anything I could have imagined. The metal frame is solid. The only thing I didn't like is the installation instructions- recommended cutting a hole almost as large as the exterior of the frame, then tightening the bolts to hold in place. I cut a hole only as big as the interior frame, so it fit snug in the door. Then I drilled specific holes for the anchor bolts.

    This is the second Endura Pet Door - Double Flap that I have owned. The first was destroyed but was not because the door was defective nor any fault of the manufacturer. The flaps on this door seal tight. We have had a lot of summer storms in the past few weeks with very strong winds and large hail and the flap did not budge. Even with golf ball size hail hitting the door it still stayed sealed and there was no rain coming through. Living in ND in the winter, the door stays sealed tight and you don't feel drafts through it. I would recommend this door to anyone looking for a door for harsh weather conditions, it really does stand up. I have two dogs a lab and a Maltese Bischon cross and she can get the flap open with no problem.
