The Max System prep cart is perfect for a wide range of food preparation, transport, serving and storage tasks. This innovative system is specially designed to work with full size food pans, food boxes, sheet pans and gastronorm size food pans. The components on this prep cart are made of impact-resistant structural web plastic. The racks and carts are designed with soft, rounded corners that are easy on walls, doors and other equipment. The heat-resistant plastic construction allows hot baking pans (350°F/ 176°C max) to be pulled directly from the oven and placed on the rack. Quiet handling and upscale design let workers move food directly from kitchen to dining room for fast restocking without repeated trips. This commercial prep cart is approved by USDA Meat Poultry Group and NSF. All casters are 5" with a non-marking swivel plate design, 2 locking and 2 non-locking.
