Ideal Pet Products Aluminum Pet Patio Door, Adjustable Height 77-5/8" to 80-3/8", 7" x 11-1/4" Flap Size, White

Nice and sturdy. Super easy to install. Included insulation and vinyl trim strip work great to eliminate drafts where pet door and slider connect. I did have to use hot glue gun to keep vinyl strip in place. Overall, a very good pet door for sliding glass door (mine is a vinyl slider) and a very good price.

perfect, price is right, easy to use, works great, and the quality is well made

This doggy door was very easy to put together and fits perfect. It also looks nice and works well for the Dogs to go in and out of the house as they please. As much as I like it overall, you must know that this door is very flimsy. This door will NOT protect you at all from intruders. It would be extremely EASY to break this door down and have access to your home.

It's well-made and sturdy. It was a little tall for my sliding glass door, but that was my fault in measurement. It was an easy fix, I cut a few inches off the top with a grinder and Bob's your uncle. Instead of integrating it into the glass door track, I put it in the screen door track. This way I can lock the glass door easily. This will be suitable for the summer, but I may have to rethink it for winter.It does take up part of the doorway, but we can all squeeze through. It didn't take long for our two 3-year-old cats to figure out how to go in and out. My wife and I are pleased with this cat doorway and I believe you will be as well. Just take the time to measure the height of your sliding glass door correctly.

I saw pet doors for sliding glass doors and prices up to $1,000. Some advertised dual pane glass as how much cold air comes through these things can be a concern.I chose this door as I wasn't sure the value was there for anything more expensive. It was easy to install with the exception of it being a really tight fit to get it standing upright inside the sliding door track. The house I bought had a lot of things put in it by someone with no construction trades experience. So the challenge getting the door up could be from the previous owner not having installed the door properly in the first place. But, with a little help from a rubber mallet, I got the door up.It does require a lot of additional weather stripping besides what they give you with the door. And some creativity with it.About getting your petsto use the door, I had read one reviewer had cut the door flap in half, removing the bottom half completely. They were going to buy another door later after their pets adapted to it. You don't need to do that because you can just unscrew the door and substitute a more lightweight piece of vinyl or plastic. I chose to use bubble wrap because that was handy.Everything pertaining to the flap gets installed from the outside, so you just take the cover piece off that goes over the screws whose tips end up on that side after you screw the three screws from the side of the door inside your house. The flap goes on the outside of the door.One of my cats learn how to go in and out on day one with the original flap. The second did not trust it so I had to open the flap to let her in and out. My third cat wanted to give it a try but I could see he didn't like getting used to the weight of the flap on his back as he came in and out.So, I just taped the flap up on the door from the outside to keep it up so no one would feel it and let the bubble wrap hang down. If you cut the bubble wrap to serve as a substitute for the hard flap while your pets are getting used to going in and out, if you cut it very slightly larger than the original flap, you won't experience cold air get in getting in.My two other cats are still in training on day two and I think they will adjust to it pretty quickly now that they're just going through bubble wrap. Eventually I'll lower the original flap more over time and I will gradually work towards removing my homemade bubble wrap flap as they get more comfortable with it.

Excellent quality item, except for one issue as noted below. The Ideal door has a simple flap that is either open or shut, which is fine if you only have one cat and you are onsite to insert or remove the panel that prevents entry. However, we have two cats each with different needs. We have an electronic cat door that we can program so that both cats can come in at any time, neither cat can go out when it's dark, and only one cat can go out in the daytime (other cat is inside only). We removed the pet door from the bottom section of the Ideal patio panel. The 6 screws came out easily without damaging the plastic panel. (We removed and installed the panel several times in the course of figuring out how we were going to modify the Ideal door. Then we had a local plastics company create two lexan panels with the cutout and screw holes needed for our electronic cat door. We used clear silicone to bond the clear plastic panels to the outside and inside of the patio panel. Then we inserted the electronic cat door and screwed it in place. The only complaint I have is that the patio panel is slightly bowed along the edge that meets up with the sliding door, making it very difficult to configure the weatherstripping to make a good seal. I didn't take a star off for that, because it was my fault for not checking the fit before altering the door. (The old Ideal Pet Door, which was too narrow for the electronic cat door, does have a straight edge.) So my recommendation to buyers is to carefully check that the edge is straight before doing any customization. Obviously I can't return it now that I've glued the lexan panels to the door. The workaround for the poor fit is to buy some very thick but pliable weatherstripping and to install the provided lock or a separate drop bar, applying a bit of pressure to close the gap. We are renting, so we got permission to install the drop bar (which requires drilling into the sliding door frame).
