Endura Flap Double Flap Wall Mount
Step 1 Measure your Pet
- Tape the provided template onto the wall in the desired location. Use a level to straighten the edges of the template.
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.
Step 3 Drill Holes & Rough Cutout
- Drill the marked 3⁄8” (9,5 mm) holes through the interior and exterior walls
- Now, cut the opening out along the lines
Step 4 Check Weather-Stripping
Step 5 Assemble Tunnel
- 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
Step 6 Bend Tunnel Tabs
- Bend the frame attachment tabs on the two smaller tunnel pieces 90 degrees upward along the perforations
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
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.
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
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
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
Step 14 Insert Hole Plugs
- Tap the hole plugs into the Interior and Exterior Frames
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.
