  • Largest dog door on the market
Color: 81" Sliding Door Size: Xlarge - 1 Flap
The media could not be loaded. We have two large dogs and it has been a challenge to find a dog door that is big enough for them to go in and out. This dog door has been a dream come true for us. We do not have to get up and down to let our dogs out anymore. We have a Rhodesian Ridgeback that is 150 pounds and a Pyrenees poodle mix that is 75 pounds. They can go in and out of the very large Dog door with ease. So far, we have not had any issues with bugs or other animals coming through the door. Seems to have a really strong magnet on the flap. There is a locking mechanism that does fit very snuggly. I always make sure to have the mechanism locked so when the dogs go in and out of the door, it does not dislodge the door for any reason. It seems to be a good price for a good quality door. The only con that I can see is that I cannot find a replacement flap and magnetic parts by that company. I will have to search for generic options for when the flap rips. I would assume with these large dogs eventually it would rip. Easy setup! The only con with the door is occasionally if there’s a really strong wind, the flap does seem to flop open and close occasionally. My cat did try to escape once, but quickly came right back in in fear of the outdoors. ... show more

  • Super easy to Install
Color: 81" Sliding Door Size: Xlarge - 1 Flap
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. ... show more

  • Great door
Color: 81" Sliding Door Size: Large - 3 Flap
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. ... show more

  • Sturdy Pet Door that Fits Out Patio Door Well.
Color: 81" Sliding Door Size: Large - 1 Flap
I recently purchased this Sliding Glass Pet Door and it’s been a great addition to our home. The installation was straightforward, the instructions were clear, and the door fits securely in the track of our sliding glass door. I also watched a youtube video they offer to help with the installation. Our pet learned to use it very quickly and now goes in and out without us having to constantly open the door. The flap closes well and helps keep the cold and bugs outside. The materials feel sturdy and well made. I was also impressed with the customer service. The seller was very responsive and helpful with my questions about extra locks for the access door. Overall, I’m very happy with this purchase and would recommend this pet door to other pet owners. ... show more
