A set of two five-tier steel shelving units, each rated to carry 440 lbs on every shelf and 2200 lbs in total, sized 30-in wide by 12-in deep by 60-in tall so the pair lines up along one wall or splits between two rooms. A reinforced support rib runs beneath each deck and rolled edges finish the frame, so loading a heavy load is easier on the hands and the shelf does not bow under it. Every shelf measures 29.5-in by 11.5-in and repositions in height, which lets one bay hold short bulk supplies while the next opens up for tall containers. What sets this rack apart from a fixed unit is that each vertical tower splits into two horizontal workbenches, and 2 post connectors are included so the halves sit level and locked rather than merely balanced. Two anti-toppling safety devices steady each unit, while non-slip foot pads stop the 21-lb frame from sliding and protect the floor underneath. The decks are thick MDF carried in a rustproof metal frame, a pairing that takes damp basement air and temperature swings without warping or rusting through. Assembly uses no bolts and no nuts at all, since the interlocking posts and shelves press together in about 10 minutes, and a mallet plus 2 protective gloves are packed in the carton. The finished black rack suits a garage, pantry, kitchen, basement or warehouse, and a second identical unit means twice the run of shelving without a second purchase.
