INSTALLATION INSTRUCTIONS

Step 1: If you have not yet measured your pet, watch this video on how to measure your pet to ensure the pet door will work.

Tape the provided template onto the wall in the desired location. Use a level to straighten the edges of the template.

The top edge of the cutout should be at least 1 1⁄4" (3,2 cm) above the tallest point of your pet’s back for the single flap, and 2" (5,1 cm) for double flaps.

Step 2: Mark the centers of the four holes using a pencil or nail. Remove the template.

Drill a small hole in the middle to peek into the wall to check for wires/pipes. If you’re clear, move on to the next step to drill through the marked holes.

Professional help is recommended if you are unfamiliar with these processes.

Step 3: Drill the marked 3⁄8” (9,5 mm) holes through the interior and exterior walls. If the drill bit will not go all the way through the wall, you will need to drill through each side separately. (See how on page 6.)

Use a level to make sure your lines will be straight. It is a good idea to remeasure your outline to ensure dimensions are accurate. Then cut the opening out along the lines.

Step 4: Ensure the weather-stripping is firmly pressed in the groove on both frames. 

Step 5: Assemble the tunnel onto the interior frame, without bending tabs, to understand how they will fit together.

Trim the four sheet metal tunnel pieces so that they are 1⁄4“ (0,6 cm) shorter than the thickness of the wall. We recommend using a jigsaw, but you could use other metal cutting tools instead.

Be careful to trim the correct side. Do not trim the side of the short tunnel pieces that attach to the top and bottom of the flap frame. Also, do not trim the side of the long tunnel pieces with three small holes in them that attach to the sides of the flap frame.

To reduce vibration, the pieces should be firmly clamped to a piece of wood. See the tips on page 5 for an example.

Step 6: Bend the frame attachment tabs on the two smaller tunnel pieces 90 degrees upward along the perforations.

Be careful to bend the tabs in the right direction. The tabs will break if bent more than once. Single flap tunnel pieces have a joggle (offset). Bend these tabs as shown with arrow. Tunnel pieces for double flap models can be bent once in either direction.

Step 7: Remove the two screws at the top and two screws at the bottom of the Interior Flap Frame (the frame that has a locking cover). If you removed the cover already, the OUTSIDE frame screw holes have threaded nuts in them and you can see them shine.

Attach the smaller tunnel pieces to the top and bottom of the Interior Flap Frame using the two screws.

Step 8: Slide the larger tunnel pieces onto the finger tabs on the small top and bottom tunnel pieces. Bend the finger tabs down as shown. The handle of a screwdriver works well for bending the tabs.

Step 9: Apply a bead of the provided silicone sealant along the inside of the tunnel where it mates with the interior frame, and along the tunnel seams.

Step 10: Place the Interior Frame, with the tunnel attached, into the opening in the wall from the inside of the building. Place the Exterior Frame into the tunnel. A partner can help you hold the Exterior Frame. For really large dogs you may wish to support the bottom of the tunnel with a piece of wood. 

Step 11: Insert the threaded rods with the barrel nuts into the four holes in the Interior Frame (the frame that has a locking cover), and screw the threaded rods into the Exterior Frame finger tight. Check that the pet door is level and tighten the threaded rods until the weather stripping compresses fully. Be careful not to overtighten.

Step 12: With the pet door leveled and all four threaded rods tightened, wiggle the end of the threaded rods that are protuding out of the exterior frame until the ends snap off. If the rods are not long enough to grip, you can use a pair of pliers to bend the rods until they snap off. 

Step 13: Apply a bead of silicone sealant along the inside of the tunnel where it mates with the exterior frame. In addition to sealing inside the tunnel of the pet door we recommend that you also seal the outside frame around the pet door. This is especially important on the exterior frame to prevent any water from leaking into the wall and causing damage. 

Step 14: Tap the hole plugs into the Interior and Exterior Frames. You can use a rubber mallet, wood block and hammer, or a similar non-metal tool.

TIPS SORTED BY STEP

Step 1: Triple check for studs - check the bottom, the middle, and the top where the cut out would be after hanging the template on each edge including the bottom. Check for baseboard height, we suggest the step over be around 3” – 4” (7 cm – 10 cm) when going through walls, so it may be necessary to trim. Step over height needs will vary based on the pet’s size.

Step 2: Before cutting the entire opening make a small square test hole right at the bottom part of the cut out, roughly 6” x 6” (15 cm x 15 cm).  Use this to take a peek at the interior of the wall to make sure that there isn’t any wiring, plumbing, etc. This way if you do find any obstructions all you have to do is make a small patch to the wall.

Step 3: You can drill through both the interior and exterior wall, but you need a drill bit that is at least 6” – 12” (15 cm – 30 cm) long.  This can be difficult to keep straight and level and having a professional is recommended; a drill with a built-in level would help. An alternative cut method where you cut the inside and outside walls separately is on page 6 (the next page).

Step 4: When installing the weather stripping make sure to not stretch it out, because it compresses over time and you want it to keep the wiggle room.

Step 5: Cut the tunnels one at a time, by clamping them down tightly to a board to avoid vibration. Use a wooden block to guide the jigsaw for a straighter cut.

Step 6: If you do not have a partner to help you guide the rods through the opening to the other frame, you can put your hand through the door and hold a mirror or smartphone facing the hole on the outside to help you see. 

Alternate rough cut method:

This method can be easier in some cases than trying to go through both walls with one pass.

» Drill through the interior wall and draw lines connecting the outside part of the holes.

» Use a hand saw or reciprocating saw to cut out the inside sheet rock along the drawn line.

» Remove any insulation to expose the back of the exterior wall. Measuring very carefully and making sure all is level drill holes from the inside of exterior wall to the outside.

» Tape off the inside opening with a trash bag. This will prevent the dust and debris from going all over and makes clean up much easier.

» Make a mark from the inner side of the drilled holes on the exterior wall. It is a good idea to measure and level your outline from the outside, to ensure your hole will be the correct size.

» Use the pilot holes and a circular saw (use a concrete blade if you have concrete or stucco exterior) to cut out the exterior. Place a piece of cardboard under the saw to prevent it from damaging the exterior.

» Finish the opening with a reciprocating saw and if possible have a spotter inside.

SPECIAL WALL SITUATIONS

If your wall is over 8” (20,3 cm) thickness, the included tunnel will not be long enough. Your contractor can install the pet door in thicker walls by fabricating a custom tunnel. This can be done by using plywood, sheet metal, brick, or stone to line the cut out.  One frame would be attached to the inside of the house and one frame to the outside. The provided template + instructions might not be accurate in a custom installation. Different hardware* will be required depending on what you are using for the tunnel and how you are mounting the frames to the wall. In all cases it is extremely important to make sure that the tunnel is sealed with silicone or caulking to prevent any damage from water leaking into the wall. 

WALL SIDING

You can choose to place the pet door on top of the siding. If you choose this option then you will need to make sure to take care of completely caulking and sealing any gaps that you have to prevent water damage to the wall.

You can also recess the pet door frame into the siding. In this case you would make the recommended rough opening according to the template. Then on the exterior you would cut away the siding only to frame the outside dimension of the pet door. Also be sure to properly caulk and seal around the frame. Some people choose to build a frame to surround the pet door, if you do this, you’ll have to take the same precautions with sealing the wall to prevent water damage.

FAQ

I want to get the large pet door for my dog, but I am concerned about a person fitting through an x-large door.

All Endura Flap Pet Doors come with a locking cover. This cover can be used to keep your pet inside by blocking access to the doggie door. 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 inch sheet of steel. If you need to, you can purchase additional Endura Flap locking covers.

We also have a product called the Watchdog Steel Security Pet Door Cover that provides maximum security for any pet door, complete with a combination lock and all. The cover comes in sizes large enough to fit even the XL dog doors for wall 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 flaps?

We recommend cats use the Endura Flap Cat Doors for Walls. Our Endura Flap wall mount pet door has 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 offset the magnets slightly which can also decrease the magnetic strength.

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. With the Endura flap door for walls 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 talk to walk through and high enough to clear the large dog's back.

Is the flap on the interior or exterior frame for single flap model?

For the single flap wall mount, the flap is attached to the interior frame. If you live in a very cold climate, we'd recommend the double flap model to keep snow out of the pet door tunnel.

How do I know what size is best for my dog?

When installing the Endura Flap wall 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.

Is a single flap enough for winter weather?

A single Endura Flap on an exterior door 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. A short explanation is that you will need to buy a new tunnel, outer frame with flap and installation kit. The only item you will keep with your single flap in the wall pet door unit is the interior frame with flap.

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.

What material is the tunnel made out of?

It is sturdy aluminum.

Why is there a difference in flap size for the single versus the double flap models?

Since each flap 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 as they enter or exit.
