Step 3
Cut Cat flap opening
Drill 13 mm (½”) holes in inside corners and center of top angle of drawn template (
fig. 3a
).
Helpful tip:
Use both hands to hold drill steady and straight at a 90° angle.
Helpful tip:
Before cutting Cat Flap 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.
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. This is necessary for the Cat Flap frame to fit correctly (
fig. 3B
).
Helpful tip:
Use proper saw blade length and type according to door thickness and material. 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.
Helpful tip:
If cut piece does not easily come out, check other side of door to make sure it has been cut.
Step 4
Install Cat Flap
Before putting away your jigsaw, place Interior Frame (frame with flaps) inside the cut-out on the
interior side of the door to check the fit. Then place the Exterior Frame into the exterior 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.
Measure the thickest part (
t
) of cut-out. Note this measurement (
fig. 4a
).
Before installing Cat Flap, 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 to select which screw to use and if it needs to be
trimmed (
fig. 4B
).
Helpful tip:
Remove pencil marks and make sure surface is free of debris and shavings before installing frames.
