Cut Pet Door Opening
3A
Drill ½ inch holes in inside corners and center of top angle of drawn template.
Helpful Tip:
Before cutting pet door opening, apply painter’s or masking tape on jigsaw blade
guide and along outer edges of drawn template to help protect door surface from marks and scratches
during cutting.
3B
Beginning in one of the holes just drilled, cut along the drawn template lines. After cutting out the
opening, you may need to recut to square the opening for the pet door frame to fit correctly.
Helpful Tip
: Use proper saw blade length and type according to door thickness and material (for
example a wood blade for a wood door and a metal blade for a metal door). Cut slowly using both
hands to hold the saw steady and straight at a 90° angle. This will prevent the blade from cutting
unevenly between interior and exterior sides of the door. If cut piece does not fall out, check underside
of door to make sure exterior side has been cut.
Install Pet Door
Before putting away your jigsaw, place interior frame (frame with flap) inside the cut-out
and check the fit. Then place the exterior frame into the underside of the cut-out to check the fit. If the
frames do not easily fit inside the opening, you may need to recut opening before proceeding with
installation.
4A
Measure the thickest part (T) of cut-out. Note this measurement.
4B
Before installing pet door, you need to determine which screw length is needed for your installation.
Depending on your door thickness, the screws may need to be trimmed with a hacksaw or screw cutter.
If the screws are too long, the finishing plugs will not fit. Use the Screw Selection Guide (Chart 1) to
select which screw to use and if it needs to be trimmed.

Helpful Tip:
Remove pencil marks and make sure surface is free of debris and shavings before
installing frames.
