Endura Flap Thermo Panel Pet Door for Sliding Glass Doors | Heavy-Duty Aluminum Frame with Secure Locking Cover | Energy Efficient & Easy Install | Black, Small Flap, 74.75"-77.75" Slider Height

Excellent quality. Looks great. Took a little encouragement to get my family's dogs (a senior 17 lb terrier and a 28 lb terrier) to go through it the first few days, but once they got the hang of it, the've been using it non-stop without any problems. We tried fresh chicken/meat, etc., which did not help at all (one of the dogs is incredibly stubborn and does not like new things - it was just a matter of him watching the other dogs go through it for a few days, and then he started to use it on his own). One tip: removing the magnet at the bottom of the flap helped make it a little easier to push open for them as they learned (we had to push it partially open for them for a day). My own 21 lb rat terrier was familiar with dog doors and loved it from the first try. Highly recommend.

Quality on this is amazing! Much better than any other pet flap I have gotten and there have been many. I had a handyman install and it is permanently fixed on to the stationary panel of glass with MANY screws and it is very secure. It would not be possible to kick this door in and I do not feel it reduces the security of the home in any way, actually I believe it increases it since now the big door can be closed and the pets can still visit the outside.The pet flap itself is a bit heavy, but would stand up to winter snows and blustery breezes.. it comes with an adaptor to keep the pet flap open but I am a mean lady and make my fur babies work to escape the house.. or to rejoin my company!

You get what you pay for - and this one is excellent quality.

My husband installed which took about 2min.so it was really easy ,no tools required.I have tiny Yorkies and they didn't want to "crash "through at first.There are pretty strong magnets all around but they are removable,use a butter knife ,wella,fit for a 3pound Yorkie! Thank You Patio Pacific!

Nice, First check the level of the jam, then the sliding door, install the panel and match the sliding door. Drill some small holes on the door jam and put in screws to make the panel solid. Our door has a clip on the jam side and I moved it to the left side of the panel, and now the door locks. Use this to seal the door.19.7 Feet Long Weather Stripping Seal Strip for Doors/Windows, Self-Adhesive Backing Seals Large Gap (from 5/16 inch to 35/64 inch) Soundproofing Seal Strip

Works very well... I have had this door well over a year and it has endured countless openings by my two dogs. It also works well to keep the outside heat insulated from the house.

It really keeps the hot Texas temps outside and NOT inside. I'm very happy with this purchase.

My cat absolutely loves this product! The pet door gives her freedom to go in-and-out without me getting off the couch, can't believe I ever went without it
