Middle Atlantic U4 15.5-Inch D Utility Rackshelf, 4 RU

Install was a breeze, and the shelf is definitely staying put. As always, Middle Atlantic products have great craftsmanship with all edges being well smoothed and having a great finish on the pieces. Don't forget about the lifetime warranty as well, which means I can confidently say I won't need to be buying a new shelf unless I don't have enough of the required size already.
