MaxSeal® PRO In Glass dog door MaxSeal Pro dog door for door installation

Security Boss Manufacturing LLC® is proud to introduce the MaxSeal® PRO In-Glass pet door for sliding glass doors and full panel glass doors. This model features Ultimate security with our new 1" thick metal insulated security panel. The flaps of this door utilize newly designed rust resistant hinge connections that results in your flaps lasting much longer. These hinges alleviate the pinch point of taller dogs as well as excess wear due to multiple pets using the door. All Security Boss products are hand built to order.

Single Flap versus Dual Flap Information Choose from 10 different sizes and 10 different frame color options. You can even order your interior frame a different color from your exterior frame at no additional charge. You may also choose between the single or dual flap version. The dual flap model will provide a superior weather barrier to the outside, where the single flap version can be used in very temperate climates.
