### ⭐⭐⭐⭐⭐ They Work
*by A***E on March 20, 2025*

After building a coaxial cable window pass-through for ham radio cables the window had to be left 2" higher than the fully closed position. A pair of these locks keep the window secure. It is not a a living are of the house so I have no concerns about it taking longer than latches to open the window.

### ⭐⭐⭐⭐⭐ WILL NOT FIT ON WINDOWS IF MEASUREMENT IS MORE THAN 1/4"
*by A***R on September 23, 2015*

I'd been curious about this product for a long time, and decided to buy one, which was a surprise when I noticed it came in a packet with two. I have several sliding storm windows, which I like to open occasionally to let some fresh air in, but even though the area I live seems to be safe, I felt worried about leaving them open, as there's nothing stopping someone from removing the screens and lifting the windows up to get in. I wanted to buy a few of these, but am glad I ordered one set. I hadn't really thought about how and where they would need to be attached to the windows, until I had them in my hand. I first tried the bedroom window (which is different from the rest of the house). I pushed it into place where it seemed obvious to go, and then tightened the screw after determining how much distance I felt comfortable leaving the window open. I was pleased that it attached perfectly, it was so easy, I wished I'd bought them years ago. Next I tried all the other windows, but unfortunately I couldn't get one to fit. The window in the bedroom, slides sideways, the others slide up the way. In the bedroom the part where the lock attaches, is very narrow, just 1/4", the other windows over 3/8", or 1 cm.to be precise, Unfortunately there's no way these will fit your windows, if the area it needs to slide over, is more than 1/4". I'm happy at least it will fit one window and was worth the money.
