Industrial shelving kit includes six shelves and compression clips. The box-beam shelf design and double-sided compression clips support heavy loads of evenly distributed weight. Steel shelves lock into place and can be easily repositioned in 1" increments. Corner brackets help prevent rocking and improve overall stability and rigidity. A hat channel under every shelf increases overall strength. Shelving also features a durable, powder-coat finish. Post kit with four 85" high posts is sold separately.
