Keep food and other items off the floor and out of moisture with a floor rack system. These lightweight plastic units lock together for a tight fit and create an even surface for placing your merchandise. An average floor rack system can hold 3000 pounds per square inch. They are easy to transport and can either be placed in the dishwasher or sprayed with a hose when they become dirty. A floor rack system can also withstand extreme temperatures and their open design provides proper air circulation.
