Rated 3.9 out of 5 by 24 reviewers.
Rated 4.0 out of 5.0 by Product works as described. The gate was pretty easy to install. It helps to have a second person to hold the gate when bolting to the wall. It has been up for two weeks and is doing the job. February 6, 2014
Rated 4.0 out of 5.0 by Right item for the need! We purchased and installed two of the metal 48" expandable gates, which worked very well for our needs inside our Gym facility. We needed a simple but secure way to control access to the upstairs area during public activities inside the gym area. It was a quick and easy install by our staff. The gates were secure when across the opening and when not in use they fold out of the way in a safe manner against the wall. The gates do have a place to apply a lock, but we did not use it since we have to still have access to the upstairs area in case of emergencies. July 14, 2014
Rated 4.0 out of 5.0 by Strong Quality Materials I purchased this gate as a barrier for my large dog. She would knock down or jump over any other gates that I previously purchased and eventially learned how to open them. I would have rated this product a 5, but it didn't come with hardware or instructions. The gate itself is extremely durable and made with quality materials. When not in use, it has a latch to keep it open and then swings out of the way. It takes up very little space when not in use, less than 12", so it is not as unsightly as other baby/ pet gates. It is heavy so you will need 2 people to hang it. The suggestion I have to the manufacture is to include hanging instructions and hardware. I contacted Homedepot Customer Service and they requested a manual for me. So all you big dog lovers, this may be the answer you've been looking for. May 28, 2011
Rated 4.0 out of 5.0 by Gates worked as expected. Allow for security and ventilation for the shop. Gates are simple and functional. Mounted easily to door frames. July 15, 2014
Rated 5.0 out of 5.0 by Just What I Needed! I bought this product because my dog was jumping the 40" high "dog gate" I had. This gate was easy to install, and works smoothly, takes up little room when folded open, looks perfectly fine -- and does the trick for the dog! I initially made the mistake of installing it with the one-way "security" lag screws provided, but then thought better of that, in case I ever needed to move or remove it. I was able to get the lag screws out with a vise grip, and replaced them with the same sized (5/16 X 3) regular lag screws, and am very satisfied! By the way, someone said the gate didn't come with installation instructions, but this one did, and as I said, they were very easy to follow. March 19, 2013
Rated 5.0 out of 5.0 by Security gate I bought this gate as security for my backdoor. The hardware included is exactly what is needed to install the gate. I had to drill the bolt holes first, then managed to installed it myself easier than i thought. This gate is a good alternative to those other full door security gates. Only problem is that my little chihuahuas can fit between the bars...... February 26, 2013
Rated 5.0 out of 5.0 by Easy to install, good price! Great product! Good for residential security. Cheaper and faster to order online and pay shipping, having it delivered right to your door, than having it special ordered in-store. Have been looking for a used one - finding this new one was more economical, not to mention cleaner! January 22, 2011
Rated 5.0 out of 5.0 by Just what we wanted We bought this gate to secure two old smaller french doors in our foyer that we didn't want to get rid of, but didn't feel quite secure enough with. We feel much better with this gate. It would take a lot for someone to try and get through it! May 1, 2011
