Ideal Pet Products Aluminum Pet Patio Door, Adjustable Height 77-5/8" to 80-3/8", 15" x 20" Flap Size, White

Overall, I think this is great. My dog uses it and it allows her to go in and out whenever she pleases. Installation was simple and I, as a young woman, did it by myself. The only downfall is that you cannot lock the door that you're shutting into this extension piece. It would be nice but as an alternative, I have a stick at the other end of the screen door to prevent it from even opening. FYI - I have this piece and then my screen door that closes to it. Then my glass door opens and closes normally. Anyway, it works perfectly fine and the stick helps alleviate any concern of someone trying to rob me. It's pretty sturdy for what it is. Slightly flimsy but overall sturdy. But that's because it's 1 long piece. AND my dog is a 50 english bulldog and the dog flap size is perfect for her. I can't imagine a "real extra large" size dog like a german shepherd, lab or even a retriever fitting through the flap. Maybe they could since they are long hair dogs whose bodies appear to be bigger than they actually because of all that hair. But my dog is a little bowling ball and it fits her comfortably with some extra room to not hit the sides or top/bottom when going in and out. The flap is pretty good quality too. It doesn't dangle and flap open/close with the wind. There's a metal piece that almost acts like a magnet or paper weight to make sure that flap stays down when not used. Lastly, my dog started using this immediately. It took a few rounds of treats to get her in and out but that was it. Simple. She uses it all throughout the day as she pleases. And for reals, lastly, I bought this one instead of the other ones because of lower cost. I think it had fewer reviews but they were decent. Hope this helps.

Great construction and super easy to install. We have 3 very large dogs and I small one and all of the can go through it with ease. Looks great. We love it!

It's a great door - good build. But yes, it was about 1/4" too big to fit over the vinyl lip on my relatively new sliding door. Just used an angle grinder to take that off and fits great. But maybe make the doors a tiny bit shorter to accommodate these new door styles.

I bought an xl door for my husky/pitbull dog. Easy to install and it was the perfect size for him. We had a little trouble lining and sealing it with our door, but nothing we couldn't fixed. We had it for a few months now, and it's still working.

Why did you pick this product vs others?:Works great for the dogs. Our 80lb lab fits easily through the swinging door. The magnet on the door is strong enough to keep the door closed in high wind. Heavy duty construction.

Its not a dog door its a sliding door. It has a handle . The dumbest thing I have ever seen.

Works great, fits as it should and arrived on time.

Dear Ideal Pet Products: this is the second door I bought from you guys. Good quality, reasonable price. However, just so you know. The 2nd door I bought has the 15X20 flap as I got a second dog and is 130lbs. He fits thru the new door perfectly, the door does work perfect. However, the sheer area of this much larger flap doesn't lay well. It's not tight at the sides and it's like a sail, with just a little breeze, it overcomes the magnet holder and flaps. I'm pretty handy so I will add some weight to the bottom of the flap just above the metal. I know this will help. My point is, the 3 pane flex type would solve this issue. I can't be the only having this problem. Not sure why you don't make it for this door. I would suggest that you make this door ONLY with the flex pane type and forget sending out a door with the flap that's really not working. Is there another flap that you do offer that might help me???
