Security Boss MaxSeal French Door Glass Panel with Pet Door


Security Boss MaxSeal French Door Glass Panel with Pet Door

The French Door Glass panel Insert is a do-it-yourself pet door solution that is simple to install, reversible if necessary in the future, and a very cost-effective option when compared to in-glass pet door products. These glass panel inserts are designed to work with french panel doors that have a plastic frame to hold the door's glass in place. All Security Boss products are custom-made to order.

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 homes. Single flap models are commonly used in scenarios where an insulating barrier is not required.


Door sizing 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 than the general surface of the door. The second characteristic is the measurement of the glass itself. Compatible glass inserts are one of two sizes: 

  • Medium: 21.75"W x 65.75"H
  • Large: 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 falls into the provided ranges and is held in place by the described plastic frame
