Steel shelving features a boltless design that allows the shelving configuration to form a five-shelf unit or workbench. Industrial-grade, 1/2" thick particleboard decking recesses into shelf supports, protecting the edge of the decking and preventing chipping. Solid shelves prevent items from slipping or snagging. Steel framework does not require nuts, bolts or sway braces and allows obstacle-free access from all sides. Double-rivet connection makes the shelving a very rigid unit. Each shelf holds up to 850 lb. and adjusts in 1-1/2" increments. Steel shelving includes eight protective caps for top or bottom of posts.
