Install Pet Door
5A
Optional:
If the door cut-out thickness (T) is 1” (25mm)
or more, insert the screw guides into the screw holes on the
backside of the interior frame (frame with flap and 4-way lock).
The screw guides help guide the screws through the screw holes
from the interior frame to the exterior frame.
Before putting away your jigsaw, place the interior
frame (frame with flap and 4-way lock) inside the cut-out and
check the fit. Then place the exterior frame (with assembled
tunnel if needed for your installation) into the underside of
the cut-out to check the fit. If the frames do not fit inside the
opening, you may need to recut opening before proceeding
with installation.
5B Before installing the 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 2) to select which screw to use and
if it needs to be trimmed for your installation. To trim screw,
insert binder post onto end of screw to protect thread. Using
the binder post as a guide, cut screw to correct length with
a hacksaw. After cutting to length, remove the binder post to
clean screw threads. Repeat process with remaining screws.
