The Vollrath 97168 utility cart has a sturdy "U"-shaped frame and stainless steel construction, granting it the durability and corrosion resistance needed to withstand high-volume operation. While employees are transporting the cart on its 4-inch casters, the frame has donut bumpers that protect the unit, nearby walls, and other pieces of equipment. Separated by 8⁵⁄₈ inches, the three shelves can hold a total of 500 pounds.
