A special swivel-mounted, frame-mount pin coupler with a "fish mouth" type head and rubber cushion for shock absorption at the coupling. Swivel action provides torsional relief. Designed for extreme duty, trailers, semitrailers, and doubles operation applications. Used for off and over-the-road applications, where a large amount of articulation is required.

The cast alloy steel body, as well as the clevis pin, is heat treated for strength, toughness, and durability. Wear plates in the "fish mouth" provide a replaceable wear surface to minimize drawbar movement.

For off-road applications, reduce the capacities by 25% and use with a non-swivel mount drawbar.
