A Cambro Camdolly will make catering your next event infinitely more convenient by reducing the number of trips and saving strain on your back. They can be loaded up with up to 350 pounds of food, dishes, or equipment. There are some Camdollies that are specially designed to hold plates or pizza dough boxes, but others allow for less specific applications. They are made of polyethylene and have 3, 4, or 5 inches casters, some of which lock and swivel. Some will have molded-in handles and some have security straps.
