Evergreen Pet Supplies Dog Door Replacement Flap - All-Season Weatherproof Door Seal - Quick DIY Installation for Pet Supply - Sturdy Aluminum Construction for Dog Supply - 9.75 in x 17 in, White

As with many other reviews I should of checked before ordering, flap is not long enough and leaves a gap at the bottom of the opening.

It was worth it to try these non-original replacement flaps due to amazons great return policy. I also read the reviews that said these fit much better after getting the bottom magnets free to move up to join the bottom of the flap. getting the bottom magnet free was not easy either! I was not able to get mine clean enough to freely go up and down but it is now up the extra 1/8-1/4 inch to make the flap fit now. For the savings of $50 per 2 flaps, I am happy with the product. I did also have to brush a little light powder to the inside of the flaps to keep them from sticking to each other at first when they were brand new and still a little clingly. Flap is made of what looks like quality materials, we will see how they hold up but at least at this price I could afford to replace more often.

It's too short. I saw another review mention this but figured all of the good reviews were enough. Well it's not, there's a 1/4" gap at the bottom due to them being too short. That's a lot of room for air and insects to come and go. If it's too short for mine it will be too short for yours. Originals are expensive and overpriced, but it seems like there is no alternative.

A little bit short for the pet door. Maybe 1/2" too short. I made it work. The metal strip came off the bottom after a few months. Easily repaired with duct tape. Now it's the correct length. My dogs are rough on stuff. Overall I'm very satisfied. The price was important, because I know I'll need to repair their door again in the future.

I move into a house and was super excited not to have to always get up to let my dog out back because it had a dog door already installed! Than I realized it was missing both of the flaps and I couldn't use it. I looked online for the make and model of the dog door and the website had these for more than double the cost for just one flap! And of course by some "magic" the next time I got on amazon these popped up and I ordered them! they fit perfect and my dog loves being able to go in or out whenever she wants!

Problem: Extremely hot summers over the past two years have warped the material of my original door. It was purchased two years ago. But wait, the inside door has also warped. Indicates to me that the original door flaps composition were the issue ... but it was hot enough that I am not placing blame. Good: Shipped quick, and we needed it. Sturdy material. Installation is a five minute job, and half that time will be finding a screwdriver. Very easy. Bad: A millimeter or two more on the bottom, same on the sides ... would have been perfect. It just does not fit the door. The magnet only holds it closed if there is no breeze. (Our door is 'square', it is an issue on all three hanging sides.) A bit pricey for one unit. These are double-doors I'm replacing (or planned to). A new unit, however, would be more than twice the cost of replacements and greatly complicate installation. (So not so bad.) In a milder climate this replacement may be passable. Cold weather double-doors are purchased out of necessity. I am keeping the flap, and will find a way to extend it a bit. It would be nice if the original engineers had done so. I imagine adding some longer fiber insulating strips around the outer door frame would do the trick. Critters have their freedom, and the air exchange would be reduced a bit. Perhaps mine was a one-off miss. Read other reviews before deciding. If yours was correctly measured, let me know in a review and I'll try again. (Getting darn cold here!) After one year of use: The metal strip on the bottom of the flap fell off within a couple of months. I had some metal tape, so repaired it that way. It also helped with the slight gap between the frame and door. The product just isn't air-tight enough to work in extreme environments. I guess it's time for a new door. Sticking with the brand though. Love the door ... hate how the flaps warp. Still, this replacement got us through a year, with some tinkering.

Very pleased. Perfectly sized and seals well.

Used to buy these on a different site, but the price has doubled, so this was a comparable deal with better price. Difficult to find the correct size with correct number of holes on the top to attach it. Happy with purchase.
