PetSafe Sliding Glass Pet Door - No-Cut DIY Install Doggy Door for Renters - Aluminum Frame - Adjustable Height 75 7/8" to 80 11/16" - Ideal for Large Dogs Up to 130 lb - White

I am SO glad I finally bought this! I was really worried I was about to spend almost $150 on a piece of junk but I am so glad I took the chance.I live in apartment with two cats. We prefer to keep their litter boxes outside and leave our patio doors open all the time to allow them to go in and out at their leisure. It drives me nuts that this is not safe. Not to mention in the winter and summer I either freeze or sweat in order to avoid paying heating and cooling costs! I finally decided I'd had enough.I will admit that when I was reading the reviews for this I was thinking to myself, "There is no way it's that easy to install." And I wondered if the reviews were written by the sellers. But I decided to go for it. The instructions and all the stuff it says on the box will fool you into thinking it will be difficult but it's so crazy easy! I had no trouble at all! It literally look me less than 10 minutes!My aluminum sliding patio door is about 78" in height (from top to bottom on the inside track) and the *medium* size fits in just perfectly. I used the weather stripping included to form a seal. I cut the excess off and it looks okay. I didn't do the best job of that because I placed it before I cut it, so it works fine but it doesn't look beautiful. It comes with accessories and things for added security, but since we do not own our apartment I chose not to add those. That's why it was so easy and simple to install. I'm going to use the *Wedgit White Mini Twist Tight Adjustable Sliding Window & Door Lock* or the *Master Lock 265DCCSEN Dual-Function Security Bar* to keep the sliding panel from opening.Just to say though, I have this installed on the inner door where the sliding door opens and closes. I also have an outer screen door that this thing is barely too big for. I tried it and this DOES fit (it's just a teensy bit unsteady) in the screen door part. BUT I decided to put it where it's supposed to go because I can partly shut the screen door to disguise the pet door. I live in an apartment which is not on the ground floor and from the ground and stairs at any angle you cannot tell there is a pet door installed. It fits so great with my other door and is hidden by the screen (it's barely open, just enough to allow my pets to pass through) that you can't tell it's there. Before, you could tell I had my patio door partially open. I feel sooo much safer now that you can't tell my door is open!Speaking of safety, this comes with a doohickey you slide down to block the entrance. You don't have to take the door out to do it. You slide it down over the flap in these little guides on either side and it has a magnet thing that holds it in place.For privacy, if you're worried about that, there are spray paints out there for glass which make it look frosted and you can buy stencils and things to make a pretty design. I've seen people use special paints to make a pretty glass mural, use stencils to fake stained glass, etc. I've also seen people use those big sticker things people usually put on their walls on the glass, or contact paper. Or even pieces of lace glued to the frame. There a ton of ways to DIY this to make it look custom made or match your own decor. There are spray paints which are for metal you could use on the frame if you wanted!The weather stripping and the magnetic flap do a great job of keeping out drafts, but my cats hate the flap so we tend to keep it flipped up for them. We tuck an edge of the flap into the groove meant for the security doohickey and it stays pretty well.I have plenty of room to walk past it (I'm an average sized female and my husband is on the slim side, but we have a ton of room) and it stays just fine even if the other door isn't there. It's stable all on it's own and doesn't need the other door to stay put. The full width of our sliding glass door is about 70" and the half of the door which can be used is probably about half of that maybe? With the pet door installed, it's plenty of room for one person to walk through comfortably.Super easy to remove, especially if you don't drill to add locks and stuff. Snaps in and out. So I can take it out easily if I move, or for going out of town, etc.I'm a short woman who cannot lift super heavy things. I do a lot of the DIY type stuff around my home, fixing things, building things, etc. My husband can, but he works a lot so I don't like to trouble him unless it's something I don't trust myself to do. I was able to lift and install the door with zero help. The box is very tall and a pain, but that was the only difficult part!

Perfect for apartment living! What makes this adjustable is a double spring at the top. There are installation instructions but I didn’t use them. It fits great and is solid “as is”. Excellent fit. The magnet on the flap runs the width. Strong enough that it will stay closed on a windy day but easy enough for my puppy to get through it. I didn’t care for the weather strip they provide and will probably go buy my own but that is the only negative thing I could say. Still worth the 5 stars.

The sliding pet door is sturdy and easy to install. Especially like that installation did not require any cutting. Adjustable, spring-loaded top makes it easy to slide in place and remove. My application is to use it when I'm away, so I didn't install the hardware that came with the door to make it more permanent, but it looked easy to install. The only issue I have is that it's pretty drafty and let's in outside air, particularly if the wind is blowing. The door seal that was provided did not adhere well and it fell off completely. Perhaps if I roughed up the mounting surface it would have stuck better but didn't want to do that in the event we wanted to return the door. After deciding to keep the door, I purchased some sponge window weather seal, roughed up the sealing surface. The seal stuck well and problem solved. I also wedge in my sliding glass door security bar to put pressure on the door against the seal/pet door and now have a nice weather seal to keep outside air out. Overall, the pet door is sturdy, easy to install and remove, and solved my issue to let the dog in and out when I'm not at home.

I finally got my patio panel installed. It definitely requires extra weather stripping as it seems most door frames aren't plumb. I appreciated the installation videos to better understand the directions. I ordered the wrong size door for my dog, but I was able to return it and get the correct size. My dog learned how to use the door easily enough and she fits perfectly through it. It's a good, sturdy door.

This is such a great door. We are so happy with this purchase. We got it for our cats to access their catio, we got the medium size door because our cats are 20lbs each. It’s perfect. The door is solid and so easy to install. The cats struggled with the flap at first, I worked with them for a bit (baby steps with the Orange’s you know…), now they will be coming in and out all year long, which is something they couldn’t do with our old door. I think this is the best Amazon purchase I’ve ever made!! This was a quality of life household item at a really reasonable price.
