Single Flap Door Mount

Step 1 Prep Your Door

  • If you have not yet measured your pet, watch this video to ensure the pet door will work.
  • 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.
  • Be careful not to cut too close to the bottom of the door as you may reduce the door's strength. Level the top edge of the cut-out line.

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.
  • Make sure your drill is kept level and drills all the way through the door.

Step 3 Saw An Opening

  • Using a jigsaw, cut along the marked lines, making sure to cut straight.
  • We recommend applying masking tape along the outside of the lines to protect your door from scratch marks as you cut with the jigsaw.

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.
  • Do not fully tighten screws until all four screws are inserted and the pet door is leveled.
  • Use the included installation magnet to help align the screws.

Door Thickness Screw Length
1-⅜” (3.5 cm) Short Screws (1-¾”)
1-¾” (4.4 cm) Long Screws (2-¼”)

Step 7 Screw Door Into Place

  • Once the pet door is leveled, tighten the screws so that the weatherstripping compresses.
  • Do not overtighten.

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.
