12 in. x 22 in. Extra Large Double Flap for Walls with Black Aluminum Frame

I recommend hiring a professional unless you have the correct tools and know exactly what you are doing. I wanted to feel 100% sure that I could do this job, but after reading the directions, I did not have the correct tools. I hired a contractor that charged me $200 and I think it was worth every penny as I slept good that night. The construction of this door is built very well and it kept the cold air out and warm air in.

I don't have good experience with this pet door and feel like I made big mistake to purchase Endura Flap Pet door.... for this price :( I have to replace flap already because magnets sliding and I have to removed it with plastic. Now I need buy both flaps replacement again but for the price I should probably look for new door :( Very disappointed with my purchase of this door! Price is very expensive and flaps not safe for the dogs because include magnets which one very dangerous for pets. Be prepare pay big money to replace flaps...

Very good quality, upsized to xl for our new big dog, smaller version still in great shape after 11 yrs , gave it to workmate so it’s still in use.Would definitely recommend for purchase

This product was very expensive, but it was made well, the instructions were easy to follow. It also comes with a fabulous warranty. Wish I could have found a coupon, but I can't put a price on my families security or the safety of my small pony.

Endura 12 IN. X 22 IN. EXTRA LARGE DOUBLE FLAP Pet Door FOR WALLS. This unit replaces a single flap dog door and services five dogs ranging from a 20 lb. Dachshund to a 120 lb. German Shepherd. The Endura flap has a magnetic design with a semi-rigid flap that returns to the proper closed position after each dog enters or exits. The double flap design insures both the outer and inner flap work to keep the elements out and the heavy materials don't blow open when the winds blow. The installation instructions are simple enough they provide a template and everything needed even providing a tube of caulk to seal everything. My installation however, was as a replacement and the old dog door was smaller so I suspect it would be easier on a new installation than retro fitting an old one. The unit is pricier than some others but as I found out with my old unit when the flap failed it was cheaper to replace the whole door than it was to replace just the flap. Endura provides a warranty on their units so that suggest they have faith in its quality time will tell. Only issue I had was that some of my dogs started using it immediately the double flap did not phase them but some needed a little extra incentive. Endura flap even includes some beef flavored training treats for the less adventurous ones.

The EXTRA LARGE DOUBLE FLAP dog door made by Endura is a high quality product made in the USA. The Endura dog door comes with RTV Clear Silicone Adhesive to make a tight seal around the frame inside and outside the house plus in the packing came a small package of Crazy Dog treats for training your dog. Installing you new doggy door will take a little time, have a friend help you and it will go faster and you'll have a better fit over all. The Endura dog door is worth the money, it will last for a very long time as long as you keep it clean.

Purchased the XL, and it does fit between the 16" center studs in the wall. BARELY. Flaps have stayed closed during recent heavy winds of up to 35 mph. We have older greyhounds, tall and skinny with one having a back issue, and they are able to go in and out of the door with no issues.I did install the door myself, but if you do not have much experience in carpentry or home construction, would suggest that you have it professionally installed. After all, you did just pay over $500 for this dog door.
