Customer Reviews

Chrome Plated Showcase Window Key Lock is rated 3.0 out of 5 by 1.
Rated 3 out of 5 by from Does the Job I bought two of these locks for glass cases. The locks themselves work great, but I had some trouble with the fastener that attached it to the glass. The first one set up just fine without any problems. However, the second the screw was a bit stripped and so I couldn't get it to snug up with the glass and so it just lays at the bottom of my case.
