  • Game Changer!!!!
Color: 81" Sliding Door Size: Large - 1 Flap
Not only is this sliding glass door pet door affordable, the engineering concept of a swing-out slider doggie door is just plain brilliant! We bought the regular Large size. First things first! Watch the installation video on YouTube and read through the rather vague instruction manual “twice” BEFORE you assemble anything. You will notice they don’t align in terms of the assembly steps, but they’ll help you get the job done more efficiently. Both the installation video and the written instructions could be better. ;) A single person could certainly install this by themselves, although it is definitely easier with an extra set of hands. When we assembled the door frame bracket ( ] ) the upper portion of the bracket was screwed to the side frame per the instructions. However, the top screws needed to be unscrewed when installing the patio door frame so you can extend the frame to fit the opening (don’t forget to use the little piece of cardboard as the top spacer with the sticker on it that says “save this piece of cardboard” on it). Lucky for us our door was plumb and square so no issues with that thankfully, although shims are provided. We also have a “slide rail” on the bottom track of our door so we did not need to screw the bottom frame bracket into the slider frame and it fit nice and snug so we didn’t need the T brackets either. Upon opening we saved the shipping box, opened it up and laid it on our kitchen table to use as our “work area” while we assembled the sections of the door. If you have any magnet trays or bowls, use those to keep screws from rolling around. With both of us working together, it took us just under two hours to install the door, BUT, that included a trip to Home Depot to get upgraded weatherstripping. We did not use any of the weatherstripping included in the packaging. We bought three sizes and types of white rubber weatherstripping plus upgraded ¼” “brush” weatherstripping and installed different ones around the door to get the best possible seal. Our door is sealed tight and is very snug. It snows here so a good weather seal is important. It does come with a door lock that can be installed, but that lock installation requires you to drill holes into the interior side of the sliding glass door panel above your handle, which we didn’t like. Instead we opted to use the old-fashioned screw-tight door/window frame locks for the top and bottom of the door if we need to lock the slider. The door is surprising well-built for the price. We bought a name brand pet door from Home Depot for our bedroom slider years ago that cost more money and isn’t as functional and this one is easily as good, if not better quality. We LOVE that it unlocks and swings open if we need more room or have people over. The parts all fit together well, it is nicely made of sturdy aluminum, and the locks and door flap are certainly as good as any other similar slider pet doors you would get at a big box store. Highly recommend! We have an 80 lb Labradoodle, a Sheltie and a Pomeranian, plus two cats who use this door. The magnets are pretty strong so it requires the smaller animals to push a little harder, but they all figured it out pretty quick. ... show more

  • Sturdy!
Color: 81" Sliding Door Size: Xlarge - 1 Flap
UPDATE: We have had no problems with the door after months of hard use, but had to add washers to the screws on the flap, as they were pulling loose and the flap was tearing above the screw. I am still very pleased with this door and, as I have several dogs, the flap takes a beating! No real problems in installation, but we did use longer screws in one part, just to be more secure. From the get-go, this door has been much more stable and secure than our previous sliding glass dog door, which only lasted 9 months. The flap closes securely because of strong magnets. There is a lot of weatherstripping. There are no visible gaps. We have several big dogs, and sometimes they get excited and try to go out the pet door at the same time, but it does not sound like the door is coming apart anymore! I will update if there are any problems. It is well worth the bit of extra money to get a more solid door! ... show more

  • Worth the struggle to have a dog door that swings open
Color: 81" Sliding Door Size: Large - 1 Flap
A lot of minor issues as listed with other reviews. That's why 4 stars instead of the 5. Quality of the dog door is really good overall. The magnet on the flap has a good hold, the puppies and the dog go easily in and out of it. I really like that the dog door can lock to my slider and stay secured when I'm not home. The way the slider closes now having a dog door leaves a small space where heat, bugs or rain could get in. I would suggest adding a small seal to that part of the door if anyone comes across that issue. (picture attached above) Issues we came across... -Leveling was an issue but easily fixed. -When adjusting the height of the door one of the springs popped out fully and needed to be put back in, inorder to lock the proper height in for the door. -Weather stripping that was provided was a little too thin so had to buy a thicker weather strip to close the gaps. And we applied cocking were some of the seals had small gaps where weather strip can't fit. -Some of the screw holes needed to be drilled more in order to get hardware to fit properly. -The lock to the dog flap doesn't pair well. If slider is closed and door flap is locked you need to open the slider to then unlock the lock to the flap. I don't plan on using that feature but want to make any buyer aware. Also the door for the flap does not stand up evenly when locked in the up position. It slants to the side as mentioned in another review. I'm happy with the door and love how it can open up. Its convenient and was kinda worth the hassle 😅 but I don't think I'd buy this specific one again just because of all the minor issues that we came across when installing. We had a regular dog door before that was waaaay easier to install but it didn't have the locks and ease of access like this door does. ... show more

  • Must have for any pet owner with a smaller patio door!
Color: 81" Sliding Door Size: Large - 3 Flap
Fantastic dog door!!! Door was fairly straight forward when installing, but takes a little finess to get level to keep gaps even. Tripple flap with moving magnets keep this door secure from the elements. I have a 15lb and 45lb dog who both use this door with ease. Being able to swing this door open allows us to use our patio door (which is smaller than normal) is exactly what we needed. Other dog doors take up this space and make your patio door unusable. This is a must if you have a smaller patio door! ... show more

  • Love the idea, but it is not perfect
After installing this dog door, theses are my experiences to share and some comparisons with my previous dog door. The pictures describe some of the issues encountered. First, I think this dog door is more substantial than my previous one, it is heavier and the glass feels thicker. Obviously, the major appeal is the ability to open and close the door for human access. The installation is much more permanent (with self tapping wood screws onto the frame) than wedging the dog door in between the sliding door and frame. Second, I encountered some instructional assembly issues. I'm not sure if the hinged glass panel and the hinged dog door were supposed to be installed onto the frame already (that's how they were packaged in the box). The instruction showed every piece unassembled. So it took me a minute to reorient and trace the steps. I still ended up with a few extras screws. I only had 1 option to fit the dog door in my sliding door frame track, which is in the middle of the sliding door track. I would've liked to fit the door in one side of the track or the other, but the door and the gap are both exactly the same width. So I positioned the gap on the bottom of the dog door over the middle track of the sliding door frame. Then, I screwed the dog door frame to the sliding door frame and added some seal strips to wedge the gap on the interior/exterior and top/bottom of the dog door. For now, with this dog door, I opted not to use the dog door lock. It impedes with the metal door when I try to slide it up and down to open and close. When the lock is unlocked, it also impedes with the closure of my glass sliding door. I did not use the regular door lock because I don't want to drill into my sliding door. To "lock" my door, I use a sliding door security bar, aka. a piece of wooden dowel in the door track. The dowel also helped to push the sliding door against the dog door for a better seal. Compare to my previous dog door (which had its own installation issues), I do like this door better. I really do like the ease of locking and unlocking the human door with a simple push of the locks. It took (embarrassingly) a lot longer to assemble and install this door. However, I think I am just more particular about how my sliding door operates with the dog door. I am also more aware of how my dogs sometime rushes out the door and can "abuse" and shift the door. So, I appreciate the long screws in the door frame, and I also spent more time sealing and wedging the gaps to keep the door as stable as possible. I was able to address most of the gaps all along the door. The top of the door is unleveled, but I just need to tinker with it a bit more. It is very irritating that the included seal strips are not great... the only one I think works adequately is the white, flat, rubber-like seal strip along the exterior border of the whole dog door. I think this is a great idea for dogs and humans... however, there are still several issues to work out, e.g., upgrade the seal strips which could solve over 75% of review complaints. The product still needs some reevaluation on the design, e.g., smaller dog door lock, placement of it, or widening the frame by a few cm more. When compared to my other dog door, the metal frame feels more robust and the opening is slightly taller for my huskies. The dog door flap feels heavier and thicker, but I don't think my dogs like the darker gray color... they can't see through it and they think the door is closed... finding the flap replacement may also pose an issue down the road. I wouldvebliked double flaps or something for a better seal and prevent heat/cool air loss. The single flap doesn't really align perfectly with the magnetic strip in the dog frame. Overall, I really like the whole idea of this door. There are good and negative points with this openable dog door. The price point is comparable to the traditional full frame dog door. But, everytime I find a feature I like, there is an issue with the installation, assembly, size, positioning, etc... so it requires substantial personal "customization." In the end, if I had to choose between this and the traditional wall cut out or other full framed sliding dog doors, I think I would pick this product... but it is not quite perfect and requires substantial preparation and time to make this work. ... 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

  • The best dog door for my 50lbs husky.
Color: 96" Sliding Door Size: Xlarge - 1 Flap
This item is the best. I have a 50lbs husky, and everytime we do a 2 days volleyball tournament we always put our dog to daycare and overnight, and it cost me $150-$200 per weekend. With this dog door partner with my automatic dog feeder we can leave our dog at the house. We just set up our camera to make sure everything is okay. Even with a small sliding door it's a plus that we can open the dog door also. And at night we just lock it and put the metal cover for the dog door. Over all I'm very satisfied with this purchase. It saves me a lot with the dog daycare. Easy to assemble, and one person can do it. ... show more

  • Perfect Solution for My Dogs and Daily Convenience
Color: 81" Sliding Door Size: Large - 3 Flap
I’ve been really happy with the convenience this dog door has added to my daily routine. One of my favorite features is the three-flap design — it feels much more secure and insulated compared to other dog doors I’ve owned in the past. I also really like that it allows you to still fully utilize the door itself, which was a huge selling point for me. That said, there are a couple downsides. I do wish the weatherstripping was a little better, as it doesn’t seal quite as well as I’d hoped, and unfortunately the handle has already fallen off. Installation was also more difficult than expected and definitely took some patience. Overall, I’m not sure this would be the most durable option long term, but for my needs it works perfectly and I’m glad I purchased it. ... show more
