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.

Glass Sizing:

First, determine if your glass is compatible by looking for two characteristics.  First, look on the interior of your door; the frame around the glass should have a higher profile than the general surface of the door.  Second, there will also be screws around the plastic frame that hold the glass panel. 

If your door meets the above characteristics, use either method below to determine the size of your glass insert panel:

1.) Measuring by the Frame:   Measure outside to outside of the small frame trim around your glass, and select the size below that fits

  • Medium: 21.75"W x 65.75"H
  • Large: 23.75"W x 65.75"H

2.) Measuring the actual glass   Remove the trim around your glass insert and measure the actual glass pane; select the size that matches your glass.

  • Medium: 20"W x 64"H
  • Large: 22"W x 64"H

Glass Size Chart

Size Outside Trim Size Glass Panel Size
Medium Glass 21.75"W x 65.75"H 20"W x 64"H
Large Glass 23.75"W x 65.75"H 22"W x 64"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. If you measure incorrectly there are fees and shipping costs to return or exchange.
