Please Note: Please thoroughly read the instructions before beginning installation.
Step 1: If possible, remove the door from its hinges, using a screwdriver and hammer to tap out the hinge pins. Lay the door on a flat surface for installation. Tape the provided template to the door. Be careful not to cut too close to the bottom of the door, as you may jeopardize the door’s structural integrity. Level the top edge of the cut-out line.
Step 2: Once you are certain the pet door will work with your door, drill through the holes marked on the template with a ⅜" (9.5 mm) bit. Make sure your drill is kept level and drills all the way through the door.
Step 3: Draw lines to connect the outsides of the holes using a straight-edge and/or level. Then cut along the line with a saw. If your door is less than 1 ⅜" (3.5 cm) thick, see the special instructions under DOORS LESS THAN 1 ⅜" (3.5 cm) THICK.
Step 4: Ensure the weather stripping is firmly pressed in the groove on both frames.
Step 5: Place the trim frame on the outside of the door and the flap frame on the inside.
Step 6: Select the appropriate screws (see below) and insert them into the pet door from the inside. Do not fully tighten the screws until all four are inserted and the pet door is leveled.
- 1 ¾" (4.4 cm) screws for doors 1 ⅜" (3.5 cm) thick
- 2 ¼" (5.7 cm) screws for doors 1 ¾" (4.4 cm) thick
Step 7: Once the pet door is leveled, tighten the screws so that the weather stripping compresses and the frames touch the door. Do not over tighten.
Step 8: Use the wooden end of a hammer, rubber mallet, or other non-metal tool to tap in the hole plugs. You can also place a wood block on the hole plug and tap the block with a hammer.
DOORS LESS THAN 1 ⅜" (3.5 cm) THICK
If your door is less than 1 ⅜" (3.5 cm) thick, the trim frame needs to be cut down so that the door mount can fit into the door.
Step 1: Remove the foam weather stripping before taking the frame apart. Set aside. Remove the four screws from the trim frame. Pull apart the trim frame. Do not remove the plastic corners attached to the ends of the trim frame pieces.
Step 2: If your door is 1" - 1 ⅜" (2.5 cm - 3.5 cm) thick, cut all four trim frame pieces at the first line about ⅜" (9.5 mm) from the edge.
If your door is ½" - 1” (1.3 cm - 2.5 cm) thick, cut all four trim frame pieces at the line about ¾" (1.9 cm) from the edge.
Be sure to support the trim frame (a block of wood a couple inches shorter than the piece you are cutting is a good choice) so that it does not sit on the plastic corners attached to the ends while cutting.
Step 3: Reassemble the trim frame. If necessary, cut the screws from the packet used in Step 6 (above) down to a ½" (1.3 cm) longer than your door thickness to secure the pet door. When cutting screws, thread on a nut so that once you’re finished, removing the nut will realign the threads of the screw.
Replace the weather stripping when you are finished. Make sure the piece stops and ends at the bottom of the frame.
The best way to install the pet door is by straddling the recessed area of one of the panels. Set the pet door on the flat area in the middle, side, and below the recessed panel. The frame will cross the recessed area on the top, so you will be left with a gap. The easiest way to fill this gap is to buy battens or shims from a local hardware store, and cut them to fit. When that gap is mostly filled, caulk the remaining areas to seal the pet door to the surface of the door in which you are installing it. If the space is very irregular you can also use squishy, foam weather stripping, which will compress down for a tight fit. When finished, use caulking to seal the door.
