I was pleasantly surprised by how well built this thing is compared to its price. Looks like something Dewalt would make. It even comes with dividers for the small drawers. Unless you're planning to place a hundred pound sandbag on top of it, im sure it could hold 45 pounds of small items easily mounted on the wall. There are plenty of backhole slots for screws hangers.If you're working in a shop with lots of foot/machinery traffic this thing will break after a few bumps, its plastic, and plastic breaks overtime. I suggest getting a steel organizer drawer for you heavy duty folks, but for average folk, this thing is perfect and will last years.Alot of people seem to be having problems with the smoothness of the drawers opening, what are you guts putting in these tiny drawers? 5 pound steel ball bearings?; i dont think these were made for heavy storage. Im not having any problems with them, and I actually like that the drawers are hard to open, less likely for them to fall out from a minor bump.If you prefer an organizer that is super easy to open and will literally fall out at the slightest touch, buy that Akro-Mils organizer, i have one of those and the drawers refuse to stay in place, so annoying.
