Single Flap Door Mount
Step 1 Prep Your Door



- If possible, remove the door from its hinges using a screwdriver and hammer to tap out the hinge pins. Lay the door flap for installation. Tape the provided template to the door. The top edge of the cut-out line should be at least 3” (7,6 cm) above the pet's shoulders.
Step 2 Drill the Holes



- Once you are certain the pet door will work with your door, make sure the template is level, and mark the outline with a pencil. Remove the template and drill holes through the corners just inside of the lines using a ⅜” (9,5 mm) drill bit.
Step 3 Saw An Opening



- Using a jigsaw, cut along the marked lines, making sure to cut straight.
Step 4 Check Weatherstripping



- Ensure the weatherstripping is firmly pressed in the groove on both frames. Weatherstripping indicated in red.
Step 5 Position the Frames



- Place the trim frame on the outside of the door and the flap frame on the inside.
Step 6 Position Screws



- Select appropriate screws and insert them into the pet door from the inside.
Door Thickness | Screw Length |
---|---|
1/2" to 3/4" | Short Screws (1") |
3/4" to 1" | Medium Screws (1-1/4") |
1" to 1-1/8" | Long Screws (1-1/2") |
Step 7 Screw Door Into Place

- Once the pet door is leveled, tighten the screws so that the weatherstripping compresses.
Step 8 Attach Screw Covers



- Push the four screw covers in by hand to cover the screws.
Step 9 Seal With Silicone

- Apply silicone where the two frames meet. Also apply silicone where the outside frame meets the door.
