When you need to haul heavy toolboxes without straining your back, this two-tier utility cart is built for the job. The bottom shelf alone supports up to 400 pounds and the top tray adds another 200, for a 550-pound combined capacity, backed by thick PP shelving and a reinforced rib structure that won't sag under a full load. Raised edges keep items from sliding off during transport, and a handle compartment gives you a spot for small parts so they don't roll away. Five-inch reinforced casters roll easily over thresholds, cords, and gravel, and the swivel wheels lock in place on uneven ground. With 19.29 inches of clearance between shelves, it fits bulky toolboxes or stacked bins. Made from tough PP that resists rust and stains, it wipes clean after oily jobs. The cart weighs 30.9 pounds and stands 39.76 x 17.32 x 33.27 inches, practical for a warehouse, garage, office, or yard.
