Five shelves rated at 330.7 lbs apiece give this stainless unit a working capacity that suits a commercial kitchen, a stockroom or a garage rather than light household storage. Assembled dimensions run 47.5 by 18 by 72 inches, and each tier measures 46.7 by 16.9 by 1.8 inches with 14.2 inches of clearance between levels, enough for stock pots, bulk cans, paint containers or storage totes. Shelf heights adjust along the posts so the spacing can follow what is actually stored instead of forcing contents to fit a fixed layout. Stainless steel construction resists rust and wipes clean of grease, flour and cleaning chemicals, which is what separates a kitchen-grade rack from a painted steel one that corrodes at the welds. The unit weighs 52.5 lbs assembled and bolts together with the included hardware in an afternoon.
