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 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.

We used our imaginations
We have pet goats and struggled to find a pet door large enough for them to utilize. Thank you moorepet for retailing a incredibly strong and durable custom made door. The door is wonderful and we may have convinced our neighbors to buy one as well (only for their dogs).

Great
I have a Great Pyrenese who is enormous. After measuring him even the behemoth size in that Maxiseal door was gonna be cutting it close. We got this door and installed it and it is working great. It takes up like half of our door, but with the dual flap there is very little difference that i have noticed in cooling costs so far this summer. This door is amazing. Thank you
