Single Flap Wall Mount

Step 1 Measure your Pet

If you have not yet measured your pet, watch this video 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
Triple check for studs in the bottom, middle, and top of 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" (7cm - 10cm) when going through walls, so it may be necessary to trim

Step 2 Check Wall For Wires/Pipes

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
Before cutting the entire opening make a small square test hole right at the bottom part of the cutout, roughly 6" x 6" (15cm by 15cm). Use this test hole 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 obstructions all you have to do is make a small patch to the wall.

Step 3 Drill Holes & Rough Cutout

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 here…)
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
Now, cut the opening out along the lines
You can drill through both the interior and exterior wall, but you need a drill that is at least 6" - 12" (15cm - 30cm) 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 available.

Step 4 Check Weather-Stripping

Ensure the weather-stripping is firmly pressed in the groove on both frames.
When installing the weatherstripping make sure not to stretch it out, because it compresses over time and you want it to keep the wiggle room.

Step 5 Assemble Tunnel

Assemble the tunnel onto the interior frame (frame that holds locking cover), 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
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 Bend Tunnel Tabs

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. Bend these tabs as shown with the arrow. Tunnel pieces can be bent once in either direction before breaking.

Step 7 Attach Small Tunnel Pieces

Remove the two screws at the top and two screws at the bottom of the Interior Flap Frame. 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 Attach Larger Tunnel Pieces

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 Silicone to Tunnel

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 Position Interior Frame & Tunnel

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 Attach Exterior Frame

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
If you do not have a partner to help 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.

Step 12 Remove Excess Threaded Rod

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 Seal with Silicone

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 Insert Hole Plugs

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

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.

Alternative Rough Cut Method

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

Step 1: Drill through the interior wall and draw lines connecting the outside part of the holes.
Step 2: Use a hand saw or reciprocating saw to cut out the inside sheet rock along the drawn line.
Step 3: 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.
Step 4: 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.
Step 5: 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.
Step 6: 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.
Step 7: Finish the opening with a reciprocating saw and if possible have a spotter inside.
