Endura Flap Pet Door For Walls (Single Flap) - Installation Instructions

Installation Instructions

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.
