Custom designed to handle heavy loads like masonite, sheet rock, and marble. This cart is constructed of 1 1/4″ square tubing with rounded corners to prevent damage to the products and walls. The base comes with extra reinforcements unseen on ANY OTHER sheet rock dolly. Most are weakly made with a single plate of light steel which can be bent when used. DON’T BE FOOLED—other carts can “handle” 2000 pounds, but the majority of them will break down because of their base construction. THIS ONE DOES NOT! The angled plate is made of 10-gauge steel to prevent slippage and allow easy transportation of your materials. It comes standard with 8″ rubber on cast iron casters, but 6″ gray non-marking or rubber on cast iron are also available. Contact us for a custom quotes and quantity discounts.
