Middle Atlantic SS Heavy Duty Sliding Rackmount ShelfA 50 lb. capacity and heavy duty 16 gauge steel construction are two of the defining features which make our model SS sliding shelf both functional and rugged. Capable of latching in an open or closed position, the shelf slides on ball bearings to an extended length of 14". A telescopic rear support mounts the shelf to any rack. Occupies slightly more than a single rack space.
