FAQ

How can I tell if this will fit my cat?

The simple way is to cut a hole in a piece of cardboard to the 6" x 11" flap size and see if they can get through comfortably.

Is the flap rigid?

No, the flap is flexible, it is just thicker than typical flaps.

Can you see through it?

It is kind of like a shower door, so you can see things through it, but can't really make out detail.

Does it come with a cover to lock it?

It does come with a cover that slides in on the inside.

If this seals so well will it be hard for my cat to use?

It is possible that you would need to adjust the magnets for training so check out our videos on this page for instruction on how to adjust those.

Will this keep one pet in while letting another out?

This is not an electronic door so any pets will be able to go in and out if they push hard enough. In addition, it will not prevent any stray and other animals like raccoons from getting in.

What if my wall is thicker than 8"?

The get the door mount version and have your contractor build the tunnel for you.

Is the flap on the inside of the wall or outside?

The flap is on the inside. And the pet door outside frame is designed so that the threshold on the bottom is lower than the one on the inside. This way if you do get any rain in the tunnel the water will evaporate or run out before it runs in.

Can I get a double flap?

We do have double flap doors, however, they are harder for smaller pets to push through so we don't really recommend them for cats.

Is the door loud?

It can be a little noisy when it closes, so it might not be the best choice for a bedroom if your kitties go in and out at night frequently.

I live in an area with hot summers and cold winters. Is this a 4 season cat door?

Yes! It has been tested in temperatures as low as -40° and as high as 110° Fahrenheit.

Installation Instructions

Please Note: Please thoroughly read the instructions before beginning installation. Installing a cat door in walls can be difficult; professional help is recommended if you are unfamiliar with these processes.

Step 1: Tape the provided template onto the wall in the desired location. Use a level to straighten the edges of the template.

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.

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 that 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.

Please Note: To reduce vibration, the pieces should be firmly clamped to a piece of wood.

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 the arrow.

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: With the tunnel attached, place the interior frame, 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.

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 loosely screw the threaded rods into the exterior frame. 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 protruding 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, woodblock 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" (7.6cm  - 10.16cm) 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" by 6" (15.24cm by 15.24cm). 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 to make a small patch to the wall.

Step 3: You can drill through both the interior and exterior walls, but you need a drill bit that is at least 6"-12" (15.24cm - 30.48cm) 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 sheetrock 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 the 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 cutout. One frame would be attached to the inside of the house and one frame to the outside. The provided template and 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.

*Not available through Endura Flap.

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.
