The Best Pet Doors by Design™

High Performance Custom MaxSeal Insulated Pet Doors

High Performance Insulated Pet Doors Custom doors generally are made for two different reasons:to fit an existing opening in a door, or to certain size specifications, such as the opening being a certain size for a unique situation (Giant breeds, dogs with mobility issues etc.). All Security Boss porducts are hand built to order.

Best Sealing - Best Insulating - Most Secure
The newest MaxSeal PRO design offers the very best seal & insulation along with ultimate security.
These custom doors are a favorite for customers who want to upgrade their existing pet door to a high performance unit without altering the cut in their door.

Important Note: When having a door made to a rough cut opening in a wall; it is recommended that your hole in the wall is a minimum of 1/8' larger than the rough cut dimension chosen for the custom door.

Example 1: If the hole you are installing a pet door is 15" wide x 20" high, then you multiply 15x20=300 square inches. Look in the chart below to see what range 300 falls into for pricing. Important: your flap size will be 13"w x 18"h (there is a difference of 2" in width and height from rough-cut dimension to flap size).

Example 2: If you want a flap size of 15"wide x 20"high, then you would figure the rough-cut to be 17"w x 22" (minus 2" from each measurement because of the 2" difference between rough-cut and flap size). 17 x 22=374 square inches. Find 374 in the chart below for pricing.
