Installation in Glass Doors and Windows
It is not possible to cut holes in tempered or double pane glass except at the time of manufacture.
Consult a professional glazier or glass manufacturer to install the pet door in a glass door or window.
The Big Cat Door is also designed for installation in glass windows and doors. Cutting glass is a skilled job and
should be done by a professional glazier or glass manufacturer. To install the pet door in glass, mark your pet's
shoulder height and location for the pet door using instructions listed in Step 1 under Non-Glass Doors.
Your glazier will need to cut a circular hole with a diameter of 10 ³/ " (263mm) with the center of the circle
1¹³⁄₁₆" (46mm) below the shoulder height mark. After the cut-out is made, then the pet door can be installed
using the installation instructions under Non-Glass Doors starting with Step 5B.
Sliding Glass Door or
Window Installation:
If installing the pet door in a sliding glass
door or window, the pet door should be
installed on the inner panel with the
interior frame on the inside of the house so
the 4-way lock does not prevent your door
or window from working properly.
(See Figure 1)
Installation in Walls
Follow the instructions for Non-Glass Doors using the enclosed cutting template. Additional skills, tools and
materials (such as wood framing and hardware) will be required.
4-Way Locking System
The 4-way lock is fitted on the inside of your door and allows you to control your pet's access in and out of
your home. Do not use the 4-way lock until your pet is familiar with using the pet door.
Knobs
In-Only: The in-only access option allows your
pet to enter the pet door but does not allow your
pet to exit. This access option is useful at nighttime
or if you need to take your pet to the vet. To set the
pet door to in-only access, turn the right and left
knobs to the upright position with the locks inside
the flap opening.
