Review: Love that it adjusts to shorter size than most - Many times I have put a cat-flap insert into a sliding glass door and bought a drop bar security lock so the door can still be quickly and easily locked, only to find the bar is jut a bit too long for the space remaining after the cat-flap insert is in. Then you have to install something at the top of the slider, or bend and move a dowel in the track every time you go in/out. Not so with this lock! It has a very adjustable length, even quite short if needed, and I was able to get it installed perfectly. Installation was easy, I put it in myself (female, 60) using my cordless drill/driver. I did not trust the adjustable black piece to hold the lock enough to prevent beak-in, but that was easily addressed by drilling a small through both overlapped metal "tubes" using a bit made for metal, then adding a set screw that fixed both tubes together, to make it even more robust. I actually added two set screws for good measure. And I put a little wire loop on the wall where it raises when open, to hold it when it's in the up position, so we don't lock ourselves out by the bar accidentally falling after closing (it hasn't yet, but it will become looser with use). My pro tip: if you are also using this with a cat-flap insert: go to the home improvement store and buy a roll of black EXPANDABLE foam weather strip to put on the vertical surface of the cat flap where the original slider door rests against it. The expandable weatherstrip comes in a fairly flat roll but when unrolled it expands. I got the .5-inch size and it was narrow enough to go on the insert yet absolutely perfect to allow for variations in the vertical surface. No gaps! The compressible weatherstrip plus adding a set screw to this bar lock also allowed me to get a very tight fit between the bar and the slider, making it very secure against anyone trying to wiggle it loose. If you have a 6-foot-wide sliding glass door, this lock will fit even with a medium size pet flap. So, I highly recommend this product.
Review: Good quality, easy to assemble. Very pleased - This safety bar is very easy to assemble and made of very high quality material. Was simple to adjust and makes for an easy solution to adding more security to my sliding door. The feature of storing it up when not needing it to be in use is very nice also.

### ⭐⭐⭐⭐ Great Product. Needs Super Strength Tape for the vinyl door frame.
*by J***E on December 15, 2025*

Was perfect. I didn't want to put screws in my sliding door so I used Hot Glue to hold the little thing that holds the tip. I didn't think it would work but it did, for 3 days. So I used 3M super strength molding tape. That will hold forever. The makers of this product should reach out to 3M and make a pre-cut piece of tape part of this package.
