Economical TENNSCO Stur-D-Stor Steel Shelving stores your industrial, wholesale, or retail merchandise. Extra strong 14-gauge uprights combine with 16-gauge shelf supports and 5/8" thick particleboard shelves to give you 1000-lb. capacity per shelf (evenly distributed). Shelves adjust easily in 1-1/2" increments. Assembly is totally boltless—only a rubber mallet is required to snap the shelf supports into the uprights. Can be assembled as a 5-shelf unit or as two separate units (one two-shelf and one three-shelf). Ships unassembled. Made in USA.
