E-SDS Large Replacement Door Flaps for Dog and Cat, Doggie Replacement Flap Doors Compatible with PetSafe PAC11-11039, Size 10 1/8" X 16 7/8"

Thanks for a great product and exact match to original.

The overall size is correct the durability is great they are nice they are thick they are flexible and the magnets work good. The only problem I have with them is the connection holes for holding them up are just a little bit high so the door hangs just a smidge low so it buckles and doesn't line up completely right at the bottom. That also makes it a little less airtight than I am used to and it makes it hard to slide in the solid doggie door. It's not a huge problem it's just a slight misalignment that's more of an annoyance than a problem. But my OCD says I have to fix it so it hangs better especially with winter coming up

This was an exact fit, perfect install like the original. My on complaint is in the cold, it's stiffer than the original.

6 Siberians and Pomskys constantly using the door and it holds up well! I buy extras because my kids have a habit of laying doorway with head half inside and half outside. This makes it get out of shape. With extras I can change out clean up and lay flat to put back in shape. I change out every 4 to 6 months. Cheaper if you buy 2 at a time so we'll worth the money.

Nothing

Easy to install, works well keeping elements out and looks great

My Australian Shepard fits thru this size with no problem. This was an existing homemade doggie door from previous owner and needed a make over . I had left over cabinet hardware screws then found some small nuts that fit. I also used a small washer in the screw end. My dog runs in and out all day as if she’s on fire. She loves it

The factory flap wrinkled at the edges over time and formed air gaps that let heat out in winter. The new flap is more rigid and flat, sealing the gaps.
