This 7-tier rolling rack packs 94 bins, 64 medium blue and 30 large gray, into a single double-sided tower you can access from either side, so two people can pull parts at once in a busy shop or classroom. Each bin has a label slot for quick sorting, and a peg-back mount holds every bin snugly to the steel frame so nothing shakes loose while you're rolling the rack around. Four rubber swivel casters, two of them lockable, let you steer the whole unit with a side handle and park it securely once in place; each tier supports up to 88.18 pounds, and the rack carries up to 500 pounds standing still or 360 pounds while rolling. A flip-top reversible lid on top adds extra storage space for the tools you reach for most. Built from powder-coated Q235 steel with impact-resistant PP bins, the rack measures 35.43 x 19.69 x 49 inches and weighs 57.32 pounds, ready for garages, warehouses, or busy kitchens.
