Abstract: The rotatable wheel assembly includes an axle and wheels. Mounting arms with mounting pins or L-shaped rods are coupled to the axle and may include end caps covering portions of the mounting pin or rod. The mounting pin or end cap is inserted into a receptacle on opposing sides of a cooler. Alternatively, the mounting arms may have an eyelet that may be rotatably coupled to a mounting stud on each side of the cooler. The assembly may be placed in a resting or rolling position along the cooler body. In the resting position, the assembly rests or snaps into a groove along the side of the cooler and out of contact with the surface. The assembly can be rotated from the resting position to a rolling position with the axle positioned under the cooler and the wheels in contact with the surface to assist in transporting the cooler.
