Hand Truck 3-In-1 Pu Wheel/Castors Red

The secret lies in the rear swivel castors, mounted on an adjustable extension. Swing the castors out of the way for a standard 2-wheel hand truck, or mount them at 45 degrees for a 4-wheel angled sack truck with highly mobile rear castors. Leave the castors flush with the frame for a stable flat-bed platform truck.
