Superior Office Services sells a lot of different racking and shelving brands and styles. Metro racking is one of our top sellers, however, we just started carrying this “generic” metro racking, it’s manufactured by Lorell. Every bit as sturdy, this racking supports up to 1000lbs on each shelf! And you cannot beat the price. If you are running them down a wall, you can save money by ganging them together with our “add-on units” which consist of 4 shelves and two posts. Add casters to make them mobile.
