Height without floor area: this rack runs 60 inches tall on a 30 by 12 inch base, taking up about the width of a doorway while carrying 2200 lbs across five decks rated at 440 lbs each. Every 29.5 by 11.5 inch shelf is thick MDF board laid on a rustproof metal frame, and each one adjusts in height, so the gaps can be set once for what actually gets stored rather than accepting fixed spacing. A reinforced support rib beneath each deck resists the slow bow that develops when weight sits in the middle of a span. Two anti-toppling safety devices anchor the rack, which is the sensible precaution on any narrow unit loaded toward the top, and non-slip foot pads keep the base planted while protecting the floor beneath. Rolled edges around each shelf take away the raw metal lip that catches a forearm during loading. Two post connectors ship with the rack and allow one vertical unit to be reconfigured into two horizontal workbenches, so the same parts change role as a space changes. Assembly is an interlocking process needing no bolts and no nuts and takes around ten minutes, with a mallet and two pairs of gloves supplied. The rack weighs 21 lbs empty and suits a garage, pantry, kitchen, basement, or warehouse.
