French Door Glass Panel
with the MaxSeal® Pet door Installed

Dual Pane Glass Insert with Pre-Installed Pet door

Dual Flap, Ultimate Security Pet Door in Dual Pane Glass

(White pet door frame with white security blocking panel)


The French Door Glass panel Insert is a Do-It-Yourself pet door solution that is easy to install, reversible if needed in future and a very cost effective option when compared to in glass pet door products. These glass panel inserts are made to be compatible with french panel doors that use a plastic frame to hold in the glass of the door. All Security Boss products are hand built to order.

This is easily determined by two characteristics. First, look on the interior of your door and see if there are screws around the plastic frame that holds in the door glass. This frame also has a higher profile that the general surface of the door. The second characteristic is the measurement of the glass itself.

Compatible glass inserts are one of two sizes:
21.75"w x 65.75"h
23.75"w x 65.75"h

Note: These glass inserts will not fit every french glass panel door. Only those that have glass that fall into the provided ranges and are held in place by the described plastic frame.

The MaxSeal® pet door is available in dual or single flap versions. The dual flap model is recommended for customers seeking an ultimate weather barrier for their home. Single flap models are commonly used in scenarios where an insulating barrier is not required.

    I’m very surprised

    Posted by Mary on Jul 7th 2021

    I had serious doubts about whether this insert would actually fit my door properly- and doubts about my ability to “easily swap out the glass”. I have to say, my doubts were completely unfounded. Once I unpackaged the insert, I read the instructions and watched a quick YouTube video. My husband (who is not very handy) and I switched out the glass in about 15 minutes. It really was that easy and it looks great. Pups are very happy to have more freedom and I’m happy to not be at the constant beck and call of dogs who want in and out all day. Very happy I stumbled on this product. It did take awhile to arrive from when I ordered, but I think most businesses have run into some supply chain issues this year. The wait was with it.
