I have a wooden workbench that has a large storage space underneath. So I decided to make better use of this space by adding some drawers. I chose this one after reading reviews of some of the cheaper ones that didn't seem to last as long as the reviews listed. Well I can say with confidence that they definitely live up to their rated capacity (500 pounds). I put together a 40" x 28" box, 11" deep. I've downloaded it with MANY tools and tested it works perfectly, very happy with the results.
