While this item was exactly what I needed, and the measurements were perfect for the space I put it in, the experience of assembly was difficult and frustrating. Locking washers wouldn't lock, and they were positioned UNDER shelves so that they drop out! The backing was not pre-drilled and was not wide enough to cover the item's width completely. Nailing the nails had many bouncing off the board, and flaking off the veneer of the walls. I ended up using several glues, duct tape, and metal bracing hardware from my own tool box to make it stable and secure. Very wobbly throughout assembly so HAD to do extras to make it safe for my stuff.
