PetSafe Doggy Door for Sliding Glass Doors, Adjustable Height 75 7/8″ to 81″, No-Cut DIY Install, Aluminum Panel, Ideal for Renters, for Cats and Small Dogs Up to 15 lb, (White, Small)

Requires custom installation, but worth the effort
I recently (3/2014) purchased this product after wanting one for several years for my dogs, and just got the installation finished. The product arrived as described, and was packed well. Fair warning – this product requires a custom installation on each home, and will require adjustment to eliminate gaps between the existing sliding door and the pet door. I’d call it a moderately difficult installation for a “weekend warrior” home DIY person (I do most of my own repairs around the house, i.e. install a new dishwasher, fix all the plumbing, etc, but don’t put in new floors/tile, work on AC/heating, do drywall work).I found Charlie the Pug (5/2/12) and Dave’s (6/18/2010) reviews useful for assistance with installation. Some changes to what they did in order to eliminate the gap between my sliding glass door and the pet door. I used Frost King White Rubber Foam Weather seal ¾” wide 7/16″ thick 10 foot long roll for both sides of the pet door. I put it between the pet door and the sliding door frame (the part that you will never see), and between the sliding door and the pet door. I tried the EPDM Rubber weather seal that Charlie the Pug mentions, and found the Foam to work better. I suggest picking up both and using your intuition when installing. I also put three screws at the top and bottom of the pet door from the sliding door frame into the pet door instead of the 1 that the installation instructions mentioned. This made the door much more solidly fixed to the frame. I then put two screws on the frame side as the instructions mentioned (one 12″ below the height adjuster and the other 1″ above the pet door).One major change that I made from the installation instructions was not putting the dog door bottom around the sliding door track. The bottom of the dog door has a semi-circular cut out to fit over the track that your sliding door runs on. I put the dog door between the front lip of the frame and this track so that the pet door sits as close inside of the track as possible. I found that this made the inside edge of the dog door flush with inside edge of my sliding door, and also made it much more stable since it was tightly fit between the frame and the track. Other style sliding doors may not accommodate the pet door like this, but I found it helped me out.In order to eliminate the gap, I needed compression between the pet door and the sliding door. In order to achieve this, I went with a cam action sash lock that can be bought from my home improvement stores. The one I bought was from Home Depot (http://www.homedepot.com/p/Prime-Line-Cam-Action-Window-Sash-Lock-U-9925/100166499?N=c3hcZ5yc1v). After the sash lock engages, the handle turns another 90 degrees, which provides compression between the two pieces. Brilliant! It took me 2.5 hours working solidly to eliminate the gap before I found this gem, and then my gap was gone! It also is an effective lock, as the sash lock they provide with the dog door is kind of wimpy. Because I am security minded, I also bought a security bar designed for small sliding door gaps ([…]). I have not tried this yet, but think it will be a nice addition to the sash lock for compression (eliminate gap) and security. Please note: the sash lock only eliminates the gap when it is engaged, so if I have the door unlocked, there is still a small gap between the dog door and the sliding door. I can live with this small gap, and do not really keep my sliding door unlocked unless I am going in/out of it.The dog door includes a plastic panel to put in as a security measure, and it seems solidly built. There are tracks on both sides of the flap to put the security panel. I think I may pick up a second to put on the outside for use in the winter to add an extra layer of insulation between my house and the cold midwest winters.Some other suggestions: the screws they provide are pretty weak. I broke several while installing. Got fed up and went to Home Depot and bought better screws that wouldn’t break. Follow Dave’s suggestion about the sweep between the sliding glass door and the stationary glass door, it helps to have some overlap. Be persistent in installing this door, as it is very useful and a good price. My dogs now love it, and I feel like I conquered Mt. Everest by eliminating that small little gap between the sliding door and the dog door.For sizing: I bought the Large/Tall. One dog is 67 pounds, lab/pit bull mix, who has 10.5″ between the floor and his chest/belly (rise). His withers are like 21″. The other dog is 58 pound lab/boxer mix, who has 10″ between the floor and her chest/belly, and has 20″ withers. Both dogs go through the door with ease, and the extra height of the tall riser (8.5″ on the large/tall door versus 4.5″ with just the Large door) looks like it would make a huge difference for them using it.Hope you enjoy

Almost perfect.
This door is so easy to install that I just put it in the doorway each day, rather than leaving it in constantly. That way, I feel better about leaving to run errands, or whatever. It is light weight, and the pet door is magnetic which has a clean, tight closure.The only issue I have is that the frame doesn’t fit cleanly up against the sliding glass door. There is a small seam which requires weather stripping, but the stuff that came with the door is useless. It doesn’t seal the space. I know that other buyers have devised ways to work around this, mostly by using stripping that they bought elsewhere. I don’t bother. Since I don’t leave it in overnight, or for long periods, I haven’t noticed that it is all that cold, or that it lets in bugs.My cats have resisted using it, because they just can’t seem to “get” how it works. Finally, one of them figured it out, and now uses it without being cajoled back through it. The others still act like they have never seen it before. Being cats, they will eventually suss it out. But, also, being cats, they prefer to spend all their time indoors sleeping.In any event, it is a good product. Not perfect, but almost.

everybody loves it here ,our two dogs love the freedom to go outside whenever they want , and we really like that we dont have to get up every time they want in or out , i did not attach it with screws , but just slide it in in the morning and out at night or when we are gone for the day , we now wish we had got it a lot sooner , a little pricey but worth every penny

We both love the pet door, it’s awesome, don’t have to let them in or out, works great for cats also. And saves on our heating bills, don’t have to leave the door open

The measurements are quite wrong
