Large Dog Door for Sliding Glass Door,Openable Pet Door for Sliding Glass Doors，All-Metal Framed & Panel & Lock,Adjustable 75 7/8" to 81" Slider Height -Large

This is a fantastic alternative to the old fixed-style pet doors. I’m genuinely impressed by the quality, durability, and ease of installation. For what’s currently available on the market, this exceeded my expectations. The adjustable height was accurate, and the all-metal frame feels sturdy and built to last.Functionality is excellent, and value-wise, it’s a smart investment. The included locking panel works well, and my dog had no trouble learning to use it.That said, there are a few improvements that could really take this to the next level. I’d love to see an option for a handle on either side, allowing easier open/close access whether you’re inside or outside. An adjustable hinge system rather than fixed hinges would also make installation much more forgiving—especially in cases where there’s slight flex in the frame.Even something as simple as spring-loaded hinge points could make alignment easier during install. It would allow the user to compress the frame slightly while fitting it in place, then let the springs help stabilize it as it locks into full position. That would be a game-changer for solo installers.But even with these small areas for improvement, I’m completely happy with this product. It does the job, looks clean, and has held up beautifully.

Door was relatively easy to assemble. Helps to have someone else but not necessary. I would recommend putting a lock bar on the sliding door (might need to do some cutting). Door is relatively slim so it’s easy to pass around it. The lock for the cover hits the sliding door but I just hold it open till im done. The shims on the new lock made it easy to keep it even and locks great but I had to install weather stripping on the sliding door and put the rubber strip on the new doggie door now it seems perfectly and feels very snug (no air coming thru). Bolting the bottom part is a bit confusing just do your best and make sure it’s not wobbly. Not sure how sturdy the glass is against hail so I’ll update later if it breaks 😂 large seems to fit 75 pound golden retriever. It looks a bit snug but I think it’s perfect. He is still a bit scared to go thru it. I will say that with very strong winds the flap does open and shut but it’s not nearly as bad as my old one so I don’t mind. The screws for the upper and lower locks that keep the door from opening are a bit short which might be a safety concern, I ended up using my own screw for that. Very solid build all metal. You’ll have to do some drilling into the wall to make it easier for the screws to go into the wall! Instructions were clear on everything except the part of the rail since the piece doesn’t fit snug. Will not stress enough that the extra weather stripping can be used between the two doors to prevent air coming thru!!!!! Will update later on it’s durability since it’s gonna start storming and hailing in Texas over the next few months

Let me just say this door will test your patience, the video is NO help. It took us 2 hours to get it together and a lot of cussing. There has to be an easier way, like spring load or something to make it easier to install the frame. After the frame was in, level, screwed into the sliding door frame it was easy putting the rest together. The door itself is nice and looks so much better than the slide in doggy door I previously had. It’s sturdy , the door swings open nicely. There was a small gap but the weatherstripping helped that. The 3 layer flap is stiff which is great and the magnetic strip works really well. My pups had somewhat of a problem opening it but quickly learned to put a little more paw in to it.Over all it’s a great door and worth the money.

This was super easy to install. It is a lot lighter than I though it would be but is still very sturdy for the material. The instructions in the manual are not completely clear but still easy to follow. They do provide a web address to the YouTube video which made it a lot easier. We LOVE the fact that we can open the door so we can still easily move chairs and other items in and out. The dogs are still not sure about using the door, but they will get used to it.Our original door is really old but this still fit and the door does close and seal really well. Our largest dog is 50lbs and he has already jumped on the glass and licked it and the door held very well, no buckling or bending. The quality of the materials are great. To me they material is the same as most quality storm doors.The only aspect we did not like is the plate that slides over the dog door. You can lock it so that it can not be lifted, which is great. However, the lock is only on one side. This does not hold the panel up very well when it is in the up position. The panel will lean to the side and it falls back in. We just take the panel out and leave it next to the door for when we need it. Leaving it on the door poses a risk of injury to you pet. We do recommend to the seller to add a better locking feature for hold the panel in place.All in all, it is well worth the money for my sanity. My dogs love going in and out for patrol and potty breaks. During spring and fall we just leave the doors open, but for winter and summer, that is not feasible. This door will allow our animals the ability to patrol the house and the yard as they deem necessary.
