Double Flap Door Mount
Step 1 Prep Your Door
- If possible, remove the door from its hinges using a screwdriver and hammer to tap out the hinge pins. Lay the door flap for installation. Tape the provided template to the door. The top edge of the cut-out line should be at least 3” above the pet's shoulders.
Step 2 Drill the Holes
- Once you are certain the pet door will work with your door, make sure the template is level, and mark the outline with a pencil. Remove the template and drill holes through the corners just inside of the lines using a 3/8” drill bit.
Step 3 Saw An Opening
- Using a jigsaw, cut along the marked lines, making sure to cut straight.
Step 4 Place Sill Plate
- Rest the sill plate at the bottom of the cutout with the weather stripping facing up and the outer leg on the outside of the door.
Step 5 Caulk U Shape Tunnel
- Apply caulking to seal the tunnel to the inside frame.
Step 6 Check Weatherstripping
- Ensure the weatherstripping is firmly pressed in the groove on both frames. Weatherstripping ends on the side for the inside frame, while the outside frame has an open area at the bottom to allow water to flow outside down the sill plate. Weatherstripping is indicated in red.
Step 7 Position the Frames
- Place the inside frame with the tunnel on the inside of the door just resting on top of the sill plate weatherstripping. Take the exterior frame and place it on the outside of the door fitting inside the tunnel.
Step 8 Position Screws
- Select appropriate screws and insert them into the pet door from the inside.
| Door Thickness | Screw Length |
|---|---|
| 1-5/8" to 1-3/4" | Short Screws (2-1/4") |
| 1-3/4" to 2-3/8" | Long Screws (2-3/4") |
Step 9 Screw Door Into Place
- Once the pet door is leveled, tighten the screws so that the weatherstripping compresses.
Step 10 Attach Screw Covers
- Push the four screw covers in by hand to cover the screws.
- If need be, use the wooden end of a hammer rubber, or other non-metal tool to tap in the hole plugs. You can also place a wood block on the hole plug and tap the block with a hammer.
Step 11 Seal With Silicone
- Apply silicone where the two frames meet. Also apply silicone where the outside frame meets the door.

The Best Pet Door in the Market
From order to shipping to packaging to installation - one of the best experiences we have ever had with a product. We went through 5 different doors before finding Endura Flap. They were all poorly made, using plastic parts. Not surprisingly, ALL of these doors broke within 6 months of installation. Moreover, they all had poor seals, allowing for cold or hot air to leak in and out the house. Endura Flap is well constructed using METAL and WOOD! The instructions were clear, and we were able to get the door installed quickly and easily. The seal on the flap is tight, helping keep the house warm or cool as appropriate. If you need a pet door, Endura Flap is the only way to go.
Lab door
Ordering was easy, good quality only item is it will not close automatically every time. Looked online for adjusting and seems like a lot of work, really doesn't match what is happening.. Would purchase another.
Has stood the test of time
Ours is the original model of this. This is the second time in nine years that we have had to replace the flap (as is expected with heavy use). Our dogs hit the Endura flap pet door like a barrel racing horse at the finish line...coming and going, hard. We live on an acre so they are bursting in and out hundreds of times a day (and night until after a few years ago when they came in at night after meeting a skunk and we got smart and used the door blocker at night). For the longest we had four dogs, now down to two so it has had thousands of hits. We also live in high wind area of NM, our patio faces west (dumb builder) and in spring and fall we will get straight winds of 40 mph plus with gusts in the 70s. It holds really well against the wind for about 4 and half years then weakens a bit, our sign to replace it. Again, expected. The fact that Endura flap has replacement parts and the durability of the product makes it worth every penny. Especially if you plan to stay long term in a home.
Great door
Wonderful door. Expensive, but top-quality. Have moved 3 times and have installed this door in all 3 homes.
Simple. Fast. Effective.
When the item arrived I unpackaged and scanned the QRCode to watch the YouTube installation video. I then followed the step-by-step installation process which was simple and fast. My new door looks great and works well. Just waiting for winter to see how it handles the negative Iowa temperatures and wind. So far I really like this purchase.
