Theyre well made, but theyre designed to have a screw in mounting system. The only problem is the shed we bought from Wayfair by the same manufacturer doesnt have the female screw in mounting system in it. So these were pretty worthless. I ended up having to screw them directly to the side of the shed so they probably will fall off at some point. Great idea. Too bad the manufacture forgot to put the mounting system in the shed itself.
