Rated 1.0 out of 5.0 by Don't buy Cannot use it, got struck with the paint. Need to return them. May 17, 2016
Rated 5.0 out of 5.0 by It does what it's intended to do I have some "insecure" storm windows in my sun room that someone was able to push in slightly to get them open by knocking the lock out of the track to get into my home. I am using these to help secure the windows in place. I used similar clamps in a house I rented a few years back for added security on cheap windows that could easily be pushed in far enough for the "default lock" to be defeated. These keep the window from then being slid open once the built in lock's been knocked out of it's track. They're nice for a little added security, especially for the price, it doesn't make sense not to have them. But I don't think they really replace quality locks on quality windows in the long run. :) April 17, 2012
Rated 4.0 out of 5.0 by Matches most windows, ez on and off EZ on and off. Matches white alum windows. The average builder's home window is rather cheap so it is what it is! August 27, 2009
