This Heavy Duty Tri-Ball with Pintle set-up accomplishes much more than your typical ball mount. The Triple Ball arrangement features all three popular ball sizes: 1 7/8, 2, and 2 inch balls. The steel pintle jaw clamps down to allow for towing with a Lunette ring. Use the pintle clamp in the up position for coupler towing. The solid steel 2 by 2 inch shank design gives this mount a rating of 10,000 pounds.
