Double Flap Door Mount

Step 1 Measure your Pet

  • 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 your may reduce the door's strength
  • Level the top edge of the cut-out line

Step 2 Drill Holes

  • Once you are certain the pet door will work with your door, drill through the holes marked on the template with a 3/8" (9,5 mm) bit
  • Make sure your drill is kept level and drills all the way through the door

Step 3 Trace Template and Cut Door

  • Using a jigsaw, cut along the marked lines, making sure to cut straight.
  • We recommend applying masking tape on the door so the jigsaw doesn’t leave scratch marks.

Step 4 Rest Sill Plate

  • Rest sill plate at the bottom of the cutout with the weather stripping facing up and the outer leg on the outside of the door.

Step 5 Apply Caulking

  • Apply caulking to seal the tunnel to the inside frame on the 3 sides of the U shaped metal tunnel.

Step 6 Check Weatherstripping

  • Ensure the weatherstripping is firmly pressed in the groove on both frames.
  • Weatherstripping ends on the side for the inside frame, while the outside frame has a wide open area at the bottom to allow water to flow outside down the sill plate. Weatherstripping is indicated in red.

Step 7 Position the Frames

  • Place the inside frame with the tunnel on the inside of the door just resting on top of the sill plate weatherstripping.
  • Take the exterior frame and place it on the outside of the door fitting inside the tunnel.

Step 8 Insert the 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.

Step 9 Tighten the Screws

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

Step 10 Insert the Screw Covers

  • Push the four screw covers in by hand to cover the screws.

Step 11 Apply Silicone

  • Apply silicone around the two sides and the top edge of the exterior frame, filling the gap between the frame and the door.

PANELED DOORS

The best way to install the pet door is to have it straddle the recessed area of one of the panels. Have the pet door sit 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 get 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 doggy door to the surface of the people door. If the space is very irregular you can also use a squishy foam weather stripping, which will compress down for a tight fit. When finished, use caulking to seal the door.
