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.

Door
THE BEST door you can buy I have had 2 in 17 yrs. One in our old home and one in our new home. Never an issue except I had to replace the 2 flaps one time. Guarantee you won't be disappointed. Well worth the money !

Custom dog door

Nice Door
Very nice door, great quality
-
Superb!
We are so happy we decided to buy the custom door mount instead of altering the opening cut we had.. I installed this in literally 30 minutes and my dog was using it in less than 1 minute of installing it!!!!

Outstanding!
I've never received better service in my life than at moorepet, and this door is incredible! Like fort knox, this doors pretty much impenetrable when locked! Thanks Moorepet

Replacement door
I replaced a door with this custom door and we love it. Seals great and fit right into the opening!
-
Awesome replacement door!
If you're replacing a pet door, like us, save yourself some time and purchase this custom dog door. It's a high end door, but in my opinion it will end up paying for itself in the long run.. Very pleased

What we needed
I replaced our discontinued 2 flap flap with this custom Maxseal and couldn't be happier with the results. Looks great, seals great, great service and great experience!
