Please read instructions & notes thoroughly before beginning installation.
Step 1: If you have not yet done so, check out this video on how to measure your pet for a pet door
If possible, remove the door from its hinges using a screwdriver and hammer to tap out the hinge pins. Lay the door flat for installation. Tape the provided template to the door. The top edge of the cut-out line should be at least 1 ¼" (3,2 cm) above the dog’s shoulders for single flaps, and at least 2” (5,1 cm) for double flaps.
Be careful not to cut too close to the bottom of the door as you may reduce the door’s strength. Level the top edge of the cut-out line.
Step 2: Once you are certain the pet door will work with your door, drill through the holes marked on the template with a 3/8" (9,5 mm) bit. Make sure your drill is kept level and drills all the way through the door.
Step 3: Draw lines to connect the outsides of the holes using a straight edge and/or level, then cut along the line with a saw. If your door is less than 1 3/8" (3,5 cm) thick, see special instructions on pages 4 & 5.
Step 4: Ensure the weather-stripping is firmly pressed in the groove on both frames.
Step 5A, SINGLE FLAP: Place the trim frame on the outside of the door and the flap frame on the inside. Skip to step 6.
Step 5B, DOUBLE FLAP: Apply silicone along the inside of the tunnel where it mates with the flap frame. Run a bead of silicone around the edges of the tunnel where it will meet the other frame.
Place the inside frame with the tunnel on the inside of the door to sandwich with the other flap frame. Take the exterior frame (without the tunnel) and place it on the outside of the door.
Step 6: Select appropriate screws and insert into the pet door from the inside. Do not fully tighten screws until all four screws are inserted and the pet door is leveled.
1 ¾" (4,4 cm) screws for single flaps in doors 1 3/8" (3,5 cm) thick
2 ¼" (5,7 cm) screws for 1 ¾" (4,4 cm) thick doors
2 ¾" (7,0 cm) screws for double flaps in doors 1 ¾" – 2 ¼" (4,4 cm – 5,7 cm) thick
Step 7: Once the pet door is leveled, tighten the screws so that the weather-stripping compresses and the frames touch the door. Do not over tighten.
Step 8: Use the wooden end of a hammer, rubber mallet, 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.
DOORS LESS THAN 1 3/8" (3,5 cm) THICK
If your door is less than 1 3/8" (3,5 cm) thick, the trim frame needs to be cut down so that the door mount can fit into the door.
Step 1: Remove the foam weather-stripping before taking the frame apart. Set aside. Remove the four screws from the trim frame. Pull apart the trim frame. Do not remove the plastic corners attached to the ends of the trim frame pieces.
Step 2: If your door is 1" – 1 3/8" (2,5 cm – 3,5 cm) thick, cut all four trim frame pieces at the first line about 3/8" (9,5 mm) from the edge.
If your door is ½" – 1” (1,3 cm – 2,5 cm) thick, cut all four trim frame pieces at the line about ¾" (1,9 cm) from the edge.
Be sure to support the trim frame (a block of wood a couple inches shorter than the piece you are cutting is a good choice) so that it does not sit on the plastic corners attached to the ends while cutting.
Step 3: Reassemble the trim frame. If necessary, cut the screws from the packet used in step 6 to secure the pet door so they are ½" (1,3 cm) longer than your door thickness. When cutting the screws, first thread a nut on so that after cutting, removing the nut will realign the threads of the screw.
Replace the weather-stripping when you are finished. Make sure the piece stops and ends at the bottom of the frame.
Make sure that you double check the total thickness of the door as the single and double flap models fit different ranges. The single flap fits doors from ½” – 1 ¾” (1,3 cm – 4,4 cm) thick and the double flap fits doors 1 ¾” – 2 ¼” (4,4 cm – 5,7 cm) thick. If you are using the double flap and your door is less than 1 ¾” (4,4 cm), you will need to build out with shims or weather-stripping to get the door to at least 1 ¾” (4,4 cm) in thickness for a tight fit.
The best way to install the pet door is to have it straddle the recessed area of one of the panels. Have the pet door sit on the flat area in the middle, side, and below the recessed panel. The frame will cross the recessed area on the top, so you will be left with a gap. The easiest way to fill this gap is to get battens or shims from a local hardware store, and cut them to fit. When that gap is mostly filled, caulk the remaining areas to seal the doggy door to the surface of the people door. If the space is very irregular you can also use a squishy foam weather stripping, which will compress down for a tight fit. When finished, use caulking to seal the door.

Which flap size should I get?
Don't know which size to get? Here is a measurement guide to help you out.
I want to get the large pet door for my dog, but I am concerned about a person fitting through it.
All Endura Flap Pet Doors come with a locking cover. This cover can be used to keep you doggy in. It also can be used to keep intruders from entering your home. It is made from a special polymer that is as strong as 1⁄16" sheet of steel. The door only comes with one locking cover, but you can purchase an additional one for the other side as long as you have purchased the double flap door mount.
Security consultants agree that dogs are a good burglar deterrent, especially one that barks. If you want to leave your pet door open make sure the gate to access your yard is locked and you post a Beware of Dog sign.
Can a large dog & cat use the same double flap door?
Our doors have a strong magnetic seal which may be too strong for a cat. However, if you have cats and dogs sharing a door, you can decrease the magnetic resistance of the threshold on large and extra large sizes making it easier for a cat to use. For small or medium pet doors you can also offset the magnets on the Endura once flap has been installed.
I have a small and large dog sharing this door. Will my small dog be able to open the flaps on the extra large double flap dog door?
It depends on the tenacity of your small dog. You can decrease the magnetic resistance of the threshold on large and extra large sizes making it easier for your small dog to use. You will also want to make sure the door is mounted low enough for the small dog to walk through and high enough to clear the large dog's back.
How do I know what size is best for my dog?
When installing the pet door you want it to clear the top of your dog's back by 1-2 inches, minimum. You also want the step over to be comfortable. Lastly you want the width to allow your pet to go through without touching the sides. Here's a measurement guide with tips on how to determine the correct size.
Are the panels/flaps flexible? Seems like it would trap a dog if it backed up.
The Endura Flap is slightly more rigid than other economy style flaps, but it is a safe, soft, flexible flap. It remains flexible in temperatures as low as -40°F.
Is a single flap enough for winter weather?
A single Endura Flap is extremely energy-efficient and capable of withstanding winds up to 50 mph. It is the only door which allows you to increase the magnetic strength for increased wind resistance. It is recommended for timid pets. The double flap increases the energy-efficiency further.
Does the door sound very loud when the dog goes in or out?
When the flap gets to its resting place there is a snapping sound when the magnets employ. This sound let's you know the door is doing its job sealing out the elements and keeping your heated or cooled air inside.
I do not have to contend with wind or rain, if I buy the single flap version of the wall dog door is it possible to add the second flap in the future?
It is possible, but it not simple and can be quite costly. You will need to purchase a new inner or outer frame with the flap as single flap and double flap frames are built differently.
Where can I find a video that shows the installation of the pet door?
You can find the installation video in the section at the bottom of this page.
What side does the locking cover slide in?
All locking covers slide in from the top. If you purchase a double flap model, the locking cover can be used on the inside or outside frame. If you purchase a single flap, the locking cover is on the interior frame.
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. To contact Endura Flap for door warranty email a photo to our customer service team, and we can take a look and let you know.
Are replacement flaps available?
Yes, you can buy Endura Flap replacement flaps.
Are there color options other than white?
Yes, they are available in Tan and very Dark Bronze.
I have a dog that I want to let out, but I want to prevent our cats from using it. Can the door be weighted to keep them from using it?
You can increase the magnetic strength of the door with purchasing additional magnets here. Some people have found success doing this and keeping their cats inside.
I have a concrete block wall. I believe the block itself is 8" so adding the furring strip, drywall and stucco it is 10-11". Will this door fit?
For all installation locations more than 2" thick, you will need the wall mount version.
Does this door seal tightly against the frame so air and mosquitoes can't pass through. If so, does the guarantee cover that lasting, as well?
The double flap door mounts come with a tube of silicone that can be used to seal the edges around the frame. NOTE: single flap door mounts do NOT come with silicone. The warranty does not cover any accidents or damage made by improper installation.
Why is there a difference in pet door flap size for the single versus the double flap models?
Since each flap is dual walled making them 7⁄8" thick as the pet pushes through the first flap will actually hit the second flap. This makes it so that there is a loss of about 1" of space a the top of the endura double flap pet doors as they enter or exit.
Is this a good dog door for garage door installations?
You can install this in pretty much any door application, however most doors from the house to the garage have a fire rating so you need to check your local code to see it installing it is allowed.

If I get 03PP12 2, can I just take a flap off if my cat has trouble with it?
You would have to uninstall the Endura For Doors, as you have to be able to remove the endura flap rod that holds it in the frame. It would be easier to adjust the magnets or just use a single flap not the double.
Is the Endura Flap for door mounting the same as the wall mount?
Yes! The flap and frames are identical, the only difference would be the hardware that is included for installation.
My door is 1 3⁄4" thick. Should I buy an Endura Flap Pet Doors double or Endura Flap Pet Doors single flap?
