This Vestil CSC-P black food and service cart has three shelves, lightweight aluminum posts, panels on three sides, and handles on both ends. The shelves are 20" in width and 43" in length. They are made of ABS (acrylonitrile butadiene styrene) for resistance to abrasion, impact, water, salts, most inorganic acids, food acids, and alkalines. They have a semi-textured surface for easy cleaning and keeping products from sliding and a molded lip along the perimeter to help keep cargo in place. The casters are made of thermoplastic rubber for low noise and a smooth ride. This food and service cart has a 175-187 lb. capacity per shelf or 550-lb. total capacity, and measures 40-1/8 x 20-1/2 x 43-3/8 inches (H x W x L). (H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; L is length, the horizontal distance from front to back.) Some assembly required.
