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)

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

Having one of these is a must for those who don’t want to get up and let your pet in and out all the time. Our dog uses this all the time! And it’s so easy to install, it literally takes a matter of a few seconds.It fits well, and is durable.If I were to be critical, I’d say that the insulation part of it isn’t great. The weather stripping isn’t as good as the rest of it. And the security of the door is hard to be sure of.But for the average situation, this door is PERFECT!Also, our dog is pretty chunky, and she gets in and out just fine with our door.

The product is pretty straightforward and my dog took to it almost immediately. As far as installing in minutes, this is a little bit of a stretch depending on what version of time you're using (2 hrs is still just 120 minutes after all). The door frame is sturdy, the glass is gorgeous, but thin, and the door is working just fine (for now). I do foresee the flap getting loose or the magnets not working as well in the future, but we'll cross that bridge when we come to it (I'm pretty good at rigging things so it's not a huge deal yet). Weatherstripping is cheap, why was there not enough to run the full length of the door. The frame could have had some recess on the part that touches the sliding door also. The included lock mechanism was useless for my sliding door.Pros:It's a dog door, no cutting or crazy installation stuff needed.It works as advertised.Convenience that can follow you if you rent a home and are not buying.If you're not too worried about safety you can just not screw it in place and use it for convenience during the day time and remove it during the nighttime...etc..Cons:Not enough weatherstrippingAt the top, the open area from the springloaded panel leaves a lot of room for air to escape or pass. If the panel was recessed some this may have been solved, or if there was a thin shield of some kind to slide in place once the door height is set, that would be cool, I stuffed that area with weatherstripping and then taped it onto the frame.If you live in a hot area (Phoenix here) the adhesive for the weather stripping and glass sweep will be basically useless as it will have melted...yes it's that hot here.Lock mechanism is a no go for some door designs. I would suggest including a locking arm instead. They are cheap to buy at hardware stores, but I would have happily spent a little extra on this product if necessary for them to have included something like that in the package.Conclusion:I have a hardware store less than 5 minutes away from me. I went there, grabbed up a clip lock (attaches to the sliding door track) and purchased a large roll of thin weatherstripping (enough to run the length of the door on the inner side, outer side, and opposing side for the sliding door) ($2.47). I also cut a piece of wood to just drop into the track. I would buy this again, but I do certainly hope they improve the design and think more universally even a simply lock down track clamp would have worked better than the lock and only costs about $3.00, but a falling arm would be great!
