Rated 3.9 out of 5 by 24 reviewers.
Rated 1.0 out of 5.0 by Adjustable bar does not lock in position This bar is adjustable, but what good is it if the lever that supposedly locks it at the desired length doesn't work? The door opens right up. Too bad I didn't find out until I installed the whole thing. Now I have to take it down and return it. Why make and sell something totally ineffective? Absolute junk.

Rated 1.0 out of 5.0 by Junk - Save your money Save your time and money. This is a poorly designed and cheaply constructed piece of junk. The "one size fits all" design results in something that either doesn't work at all, or fails in a short time. The universal bar is designed to expand to fit your door, except it frequently doesn't "lock" and allows the door to open about 6-8 inches. I installed this product last year and it lasted about 10 months. The replacement unit I bought today didn't work at all. Even the local sales staff agreed it was junk. July 23, 2009
Rated 4.0 out of 5.0 by good door lock It works just as described, I only had one issue with the design. It has a locking mechanism that is easy to adjust, but no way to actually lock it to a certain length once you have decided how long you need it to always be. Simple fix figured out how long I wanted it to be, and drilled a single hole and put a set screw in it. March 4, 2014
Rated 5.0 out of 5.0 by Mine Works Great! I bought for my house, my wife and I discovered that the lock on our sliding door can be opened just by moving the door back and forth to trip the spring. We went out and got this product and tested it over and over and never had one issue. Matter of fact, sometimes when I come home from work to take my dog out, I forget that it was even there because it blends in perfectly. I have recommended this to friends. April 20, 2015
Rated 4.0 out of 5.0 by SECURITY BAR This would have got a 5 Star Rating except for the Lever Activator - it needs to click into position & stay there but unfortunately it doesn't lock tight! This is crucial as it determines the size you are customising the security bar. I am going to try some sort of clip to fix this - but you shouldn't need to do this!! January 6, 2015
Rated 5.0 out of 5.0 by Good product This is a good product,just what I was looking for. Easy to install and works very well. November 5, 2014
Rated 5.0 out of 5.0 by Sliding Glass Door Security I travel a lot so I installed these security bars on all of my sliding glass doors. The bar was easy to install and function perfectly. Now my wife can sleep better at night and do not have to worry about the stupid old stick trick. October 21, 2014
