Security Boss MaxSeal PRO-French Door Glass Panel with Pet Door


Security Boss MaxSeal PRO-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 newly designed MaxSeal PRO pet door incorporates the most up-to-date design and functionality available in pet doors today. New features include a metal 1" insulated interior security panel that provides the most security of any pet door when locked. The flaps of the MaxSeal PRO have a unique aluminum hinged connection that allows the flap movement to swing more freely while also eliminating the pinch of the flap when larger dogs use the pet door, resulting in your flaps lasting much longer between replacements.

The MaxSeal PRO pet door for doors is made with high-grade aluminum material that is naturally rust-resistant. This door will not only last but will look great throughout its life of the door. The durable piano-hinged vinyl flaps are UV treated and weatherized to prevent shrinking, cracking, discoloring, and warping. Most flap brands do not hold up against harsh environments (direct sunlight, extreme temperatures, overuse, etc). Staggered stainless strike plates are riveted to the sides and base of the flap, connecting to powerful embedded magnets in the aluminum frame, creating an exceptional air seal.


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
