Step 5
Install Pet Door
Helpful Tip: Tape the flap up to keep it out of the way during the installation.
Optional:
5A.
Depending if your door is 1" thick or less, break
away core frames of the interior and exterior frames. Use
pliers to slowly and steadily bend down small sections across
frame at grooved line. Go across the frame again in the same
direction working the excess frame into a 90º angle. Next go
back across frame in the opposite direction to slowly break off
the excess.
5B. Place interior frame (frame with the flap) in cutout. Next place
exterior frame into cutout from underside of the door. Hold
frame pieces together with one hand.
5C. Drop nylon screws through holes in frame and
match screw sleeve to bottom side of each screw.
Pull up screw to position screw sleeve flush into
exterior frame. While continuing to hold frames,
tighten screws until frames come together.
Optional:
Caulk around the exterior frame (frame
without the flap) and inside threshold where core
covers meet for weather resistance.
5D. Use a screwdriver to evenly tighten screws
throughout frame. It may be necessary to adjust
screws to make sure pet door fit is correct.
5E. Cut off excess screw length with wire cutters. Hold
wire cutters flush with frame for a clean, level cut.
Helpful Tip: Any rough edges of nylon screws left by wire
cutters can be removed with a metal file.
Use a manual screwdriver to tighten
the screws. Do not overtighten.
Overtightening can strip the thread off the
screws or bow the pet door frame.
