Review on 🚪 Ideal Pet Products Replacement Flap: New Style Plastic/Deluxe Pet Door, Extra Large - 10-1/2" x 15" Flap Size: Find Now! by Jill Bethel

I am SO HAPPY with this valve replacement! The original door I bought was this: https://www.amazon.com/gp/product/B01ASL9XD0/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1(Barksbar, Large). Used heavily for a little over a year, the thing started cracking and after about two weeks it got even worse. It was the cheapest replacement clasp I could find and not even from the same manufacturer. Different manufacturers were the first concern, measurements were the second. My husband measured our door valve - the exact dimensions are slightly larger than what's listed on this valve's packaging BUT they are the same dimensions as the Barksbar; ALSO, if you scroll down on this manufacturers page, you will see that the dimensions (10.5 x 15) are SUPER LARGE - IT IS NOT! I bought an Extra Large which was the correct size 10.5 x 15. And it fits like it was made for him. SUPER happy at $16.00! Hope this helps someone!
