Product Overview
MaxSeal Custom Made Dog Doors - For Doors
The Best Pet Doors by Design
Single & Dual Flap Models Made to Order
Our custom version allows customers to order a MaxSeal in 3 manners:
1. Based on an existing cut through a door
2. Based on a desired flap size
3. Based on an exterior frame dimension
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).
Best Sealing - Best Insulating - Most Secure
Flaps are impact tested in conditions of -20 degrees Fahrenheit. Moore Pet has tested these doors in the harsh Minnesota winters and summers, we highly recommend this door.
Important Note: When having a door made to a rough cut opening in a door; it is recommended that your hole in the door 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.
Pricing for these custom doors is based on Rough Cut Dimensions
(width x height of your opening = Total sq. inches in chart below)
