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 !


| 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.
