Security Boss Manufacturing LLC® is proud to introduce the In-Glass pet door for sliding glass doors and full panel glass doors. This model features the same high performance insulating and sealing characteristics as found in the popular wall and door mounted models. This unit is specially made with a low profile exterior frame for installation in a sliding glass door. This dog door can be installed on single pane glass, dual pane glass, triple pane glass as well as commercial grades. 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. You can maintain all parts on the MaxSeal® PRO doors so that you will never need to buy or replace the door. You can always keep your dog door functioning perfectly for the life of your pet! Security Boss builds your door as ordered so that you can choose from the greatest variety of options and features. The exterior frame of the In-Glass MaxSeal® Pro Pet Door is a specially made, very low profile design that allows your sliding door to glide past the exterior frame of the pet door.
