Step 1 Measure Your Pet
- Measure your pet and make a mark at least 3” above your pet’s height on your wall, this will line up with the top of the cutout.
Step 2 Prepare Wall for Installation
- Find a location clear of plumbing, electrical and other obstructions. If you have stud construction choose a spot against one stud when possible.
- Use the included cutout template to mark out the rough opening in the wall. Make sure your lines are level. This cut out will leave space for the included tunnel material.
- Double check your template dimensions with the chart before cutting into your wall.
Step 3 Make the Rough Cutout
- Cut through your wall with the appropriate tools.
- Remove insulation inside the wall as needed. You can save some to put back into open areas of the wall cavity.
Step 4 Add a Bottom Support Stud
- Add a bottom support stud between the studs in your wall.
- Add any other supports or bracing as needed.
Step 5 Create the Tunnel Liner Box
- Create the full size tunnel liner box by assembling the tunnel material with all the painted edges facing the same way
- Attach the pieces with the provided medium wood screws as demonstrated in the diagram.
Step 6 Draw Cut Line On Tunnel
- Slide tunnel box into opening until the inside of the box is flush or slightly inside the surface of your inner wall. Mark a line all around the box at the outer wall. Remove the box from the wall.
- Relocate the tunnel box screws so they are all within the usable area of the tunnel. Cut off the excess tunnel material line.
- Cut just inside your line to make sure the tunnel does not end up sticking out of the wall after installation. It should be flush or just inside the wall surface on both inside and outside.
Step 7 Attach the Tunnel Liner Box
- Insert the tunnel liner box into the rough cutout opening. Use the provided shims to get the tunnel level and square.
- Use the provided long wood screws and/or concrete screws to attach the tunnel box to a nearby stud, brick, concrete, or bottom support.
- Trim off shims flush to the wall. You can score with a knife then snap them off.
Step 8 Apply Spray Foam Sealant
- Use the spray foam sealant to fill any gaps around the tunnel box.
- Once the sealant dries, trim off any excess.
Step 9a Prepare Tunnel for Sealing Tunnel Tape
- Make sure that the spray foam sealant is dry and that the tunnel area is clean.
- To apply the sealing tunnel tape, start at the middle of the upper tunnel and apply the tape all around the tunnel, ending with a slight overlap at the top. Make sure to press the tape tightly into the corners as you go.
- Once in place, firmly apply pressure all along the tape to activate the adhesive.
Step 9b Apply Sealing Tunnel Tape
- Cut each corner up to the outer wall.
- Fold back each piece of the sealing tape against the outer wall, pressing firmly.
- Apply caulking to the openings in all four corners, sealing the cut area of the tape to the outer wall.
Step 10 Screw in the Frames
- Make sure the four tabs are upright and snug to the inside frame. You may have to loosen the screw to rotate it into place using a Phillips screwdriver.
- Insert the inside frame and level it in the opening with the hole transfer jig. While holding the frame flush against the wall, use four wood screws to screw the mounting tabs to the inside of the tunnel.
- If there are larger gaps you can pre-bend the mounting tab toward the tunnel.
Step 11 Install the Outside Frame
- Repeat installation step #10 for the outside frame, making sure the flap(s) swing through both frames without interference.
Step 12 Seal the Inside Frame
- From the outside, apply silicone in the tunnel, around the sides and bottom edges of the inside frame. This will seal the tunnel tape to prevent water intrusion.
Step 13 Seal the Outside Frame
- Use a sharp razor blade to trim off any excess tunnel tape that is sticking out past the outside frame on all four sides.
- Apply silicone where the outside frame meets the exterior wall on the top and sides, but leave the bottom open to allow for drainage.
