U-Boat Casters and Wheels

For Carts commonly seen at Home Depot, Lowes, Retail Stores, and more! Fits UBoat Carts and Platform Trucks

U-Boat Carts are the large carts typically seen at the large hardware stores such as Home Depot, Lowes, and other large retail chains used to move heavy materials. U-Boat carts are the same carts you commonly use in order to move wood in which the cart has two larger wheels in the middle of the cart and four smaller wheels in all four corners. Most U-Boat Carts contain two 8 inch polyurethane wheels and 4-inch polyurethane wheels. We offer the direct OEM brand of Casters and Wheels seen on carts manufactured and used on all Home Depot Carts, Lowes Carts, and many other U-Boat Carts in the industry seen in many different hardware and retail stores around the USA. Don't buy a knock-off from somebody else, buy the original wheels used on these carts for the highest quality casters and wheels as well as the best performance in the industry direct from Caster Headquarters.
