Specialized Through the Glass Installation



Installing a pet door through the glass is an aesthetic and functional choice for many clients. Using the already inherent weaker insulating section of your wall (The sliding glass doors) you can install a superior insulating dog door. Our In the Glass Dog Doors are simple to install but do require the services of a local glazier or skilled handyman that has experience ordering and installing panel glass.

Maintaining the MaxSeal® door is simple and easy for any home owner. The flap connection points can be easily accessed by thumbscrews that hold each flap in place. The MaxSeal® Pet door is designed to be fully maintained by the home owner indefinitely, making it the last pet door you will need to purchase.

Security Boss® has an extensive nationwide network or qualified installation specialists that can provide you with full service installation of your MaxSeal® pet door.

Important Ordering Information
1. You will need to select the correct adapter for your glass thickness
2. Measure the thickness of your glass. We include Filler Blocks that help locate the pet door in the glass notch.
(Measuring the glass thickness may be best performed by a local glass installer)

We recommend that you contact a local glass installer to order the glass for your door with the needed notch in the corner. Please click below to review local glass professionals that can assist you. Some of these listed professionals can handle the entire ordering & installation process for you.
