Like its counterpart, the Industrial Horseshoe Roller Hangers design originates from the classic shape of the steel rounded shoe nailed into a horses hoof wall . What sets this Roller Hanger apart from the Modern is the design variation that carries the two extending parts of the "U" up and over the " Roller" or "Wheel" giving it added strength for the ability to better support an oversized door and more suited for an industrial application. This hanger mounts to the face of the door.
