Five metal tiers on this 60-in tall garage shelving unit create vertical storage for tools, bins, and supplies while keeping a compact footprint. Each thick MDF shelf measures 29.5 x 11.5 in and rests on a reinforced frame that supports up to 440 lbs per shelf and 2200 lbs in total, so heavy boxes and equipment stay securely stored. Height-adjustable shelves let you fit items of various sizes without wasted space. The boltless, interlocking design and included mallet help you assemble one tall rack or split it into two horizontal workbenches.
