The flashing attachment for wall models is a part of our exclusive water containment and diversion system. It is intended to be installed underneath the tunnel on a wall installation to shunt any moisture that might possibly enter the pet door back outside the wall and prevent any water intrusion into the house wall.
Flashing comes standard with any wall model but if you need a replacement, it is available in 12 standard sizes or we can make you a custom size flashing to fit under a custom width tunnel. Please see our sizes page for more information if you need help in choosing the proper size. Please choose a size from the drop-down box. The dimensions listed next to each size are for the passage opening the pet would use. For rough opening and tip to tip frame dimensions, see the sizing tab. The tunnel dimensions would be the size of the rough opening. If you need a custom size flashing for your door, please see our custom orders page for information or call to order at 800-646-4773.
