PetSafe Doggy Door for Sliding Glass Doors, Adjustable Height 75 7/8" to 81", No-Cut DIY Install, Aluminum Panel, Ideal for Renters, for Medium Dogs Up to 40 lb., (White, Medium)

This worked out perfectly for me. I have had two Petsafe doors previously. The newer one (23 yrs old) I accidentally left behind when I last moved. I didn’t remember the brand and was confronted with a dazzling array of doors. I was quite a job finding a small opening on,the smaller of the two heights WITH a flap cover. I was so delighted when it came and was a Pet Safe. It is almost identical to the prior one. There is an improvement. Previously the doors had a SLIDING panel on to to adjust for heights the new design has this but it is spring loaded and a bit easier to fit in. I have never used weathering stripping or hardware with these doors. I out the door in,the track and close the slider then use a piece of wood behind the slider. This door is perfect. The first petsafe door I had cost $100 40 years ago and was not as nice (but just fine) as the two subsequent. I don’t know what I paid 23 years ago but this door cost less than twice the cost 40 years ago. I consider that a bargain.I have two cats. One has a lot of pet door experience. He went right out then spent some time outside staring at the door as if thinking “how did I miss this all this time?” The other cat has no experience but has often learned things from the more adventurous cat. Have high hopes.Finally this door says up to 15nlbs. My cat that has used it is quite large at 17 lbs. He had no problem slipping through.

This is a very well made dog door by people who care about producing quality products. I am beyond happy with my Pet Safe dog door. I hope they continue to make great products at a fair price. If you need a dog door for your glass slider, you cannot do better than this brand!!!

I got this 4 days ago and it was installed quickly. Took maybe 30 minutes and that was with us messing up a few times and adding an extra step to add a piece to make it lock.The girls are finally using it without prompting them today and they love it. We don't have the flap down currently. We are letting them get used to going in and out then slowly lowering the flap so they can be worked into it as they are scared of a lot.Instructions are ok.The only thing I wish is it had a better lock and a stronger support where it connects to the door. I'm afraid it will break if the door is shut too hard.The support could easily be added in a way that stops the screen from shutting too far blocking off the dog door and not leave a gap. It would add a good strength to it.The lock we added a bracket to the panel and it lets us use the original door lock for the sliding glass door

Love it!!! I put it and and wedge my door shut with a custom measured piece of wood. I did buy wether thick 1 in strip to seal where both doors meet tho. But it was expected. This is by far a 5 star. If youre hesitated then do t be. Just get it.

Pet door works good. Like other reviewers have suggested buy the 3/4 frost king sweater rubber foam strips to place around edge of insert to help seal it. It should show up under the "other people also bought this" column on Amazon. The only thing I didn't door is dreimel the holes to secure it because I would feel safer being able to easily remove it during really severe weather.

We got this door as we have 3 Yorkies who like to make life hellish by not wanting to go out at the same time. Thus you have to get up and let one out, then a few minutes later the second and some time after that the third will decide to go. Yes I know we could just put them all out, then one stands at the door whining and one stands in the yard barking at the sky while the third uses the bathroom. And the two that didn't go will irritate you to go back out ten minutes after they come in. Yorkies are a lot like Gen Z, they complain a lot about having to do a little when it's not their way.So we go the door and installed it. It was missing the glass sweep. The latch mechanism for locking the door is so poorly explained that even after watching their video on youtube I still don't know how it is supposed to work. And it doesn't seal at all. It's design doesn't work well if you want to contain air. You end up leaving your sliding door 1/4 open when the door is installed and closed. So the two parts of your sliding door no longer meet up where the seal is. Had to put some weatherstripping in that gap to stop unabated airflow. But if you need to open the door, you will probably mess it up and have to redo it. The seal between the panel and door frame was horrible. Needed more weather stripping in there. And the seal between the door and the panel was also pretty bad. Add more weatherstripping. What I"m saying is, go to the hardware store and get a half mile of weatherstripping or order a truckload with this here. The glass of the panel is single pane, and it is not good at stopping cold. The seals in the panel around the glass is fair at best, and cold air gets through it. The gap in the upper panel let's in tons of cold air. I have a thermal camera and took some photos of the poor performance at keeping the cold out. The first photo is the sliding door and petsafe panel. The sliding door is dual pane glass. You can see how cold the petsafe door registers, 49 degrees inside the house. The sliding door glass registers 59 degrees. The dog door itself is showing 39 degrees, while it is about 25 degrees outside. Oddly enough the plastic door itself maintains a warmer temperature than the glass pane does. Installing this door made our kitchen a full 10 degrees colder than it was, and about that much colder than the next room which is not separated by a wall. We read where Petsafe says to use two of the plastic swinging doors when it's cold, but the yorkies are so small (<10lbs) that they already have to push it pretty hard to get out. Adding another would likely inhibit their desire to use it. We didn't expect it to be perfect by any means, but we did expect it to perform much better than it has for its price. I'd imagine others would find they have massive air leaks as well if they used a thermal imager.
