Flat shelf truck is ideal for use in transporting equipment, boxes or mail supplies, banker's boxes, and other bulky items on its three shelves. The bottom two shelves have 13" of clearance. Sound-damping materials are applied to the underside of shelves to reduce vibration noise. 5" casters (two with locking brakes) make it easier to cross thresholds and to transport heavy loads. Welded construction provides maximum strength and durability, and 5" casters are load rated at 125 lb. each. Flat-shelf truck also features smooth rounded handles and perforated end panels. Durable all-steel construction contains recycled material.
