How to InstallMeasure your pet's shoulder height next to your door. Use a pencil to make a mark 2 inches above your dog's shoulder onto the door. This point serves as the top of the dog door template.Prepping the Door (Optional but recommended): Remove the door from the hinges and place the door on an elevated surface (e.g. saw horses). Clamp or put a weight on the door to prevent it from shifting.Outing the Template: Align the top of this template (instruction sheet template) with the mark on the door. Make sure the template is centered horizontally and leveled on the door. Trace around the edge of the template on the door with a pencil.​Marking and Drilling: Mark the tips of the four corners of the outline with either a pencil, nail or awl for drilling. Drill a 3/8" diameter hole on each of the four corners of the drawn template. (Make sure you drill exactly at the tips of the corners). These will be the pilot holes for the saw blade.Cutting the Opening: Use a proper saw to cut the opening (e.g. saber saw, jigsaw). Beginning with one of the corner holes, carefully cut along the pencil line.Assembling Pet Door: Place exterior frame (without the flap) into the opening from the exterior side of the door. Make certain the frame is flush with the door surface. It is recommended to caulk around the exterior frame for weather resistance.Remove the slide panel and insert the interior frame (with flap) into the opening from the interior side of the door. Make sure the screw holes are aligned, hold the frames tightly in place and install the six screws. Tighten until snug but DO NOT over tighten.Pet Training: Train your pet to use the door. Have fun!
