The Express KitchQuip Wall Shelf adds sturdy storage anywhere you need it: above prep tables, in garages, closets, laundry rooms or janitorial rooms. The shelf is 18-gauge 430 stainless steel, so it resists corrosion and wipes clean without trapping food or liquid. Mounting brackets are included: 2 for shelves up to 60" and 3 for 72". NSF certified. Designed for commercial use, so minor surface marks from manufacturing are normal.
