The CURT 3-in-1 ATV ball mount has multiple features, including a 1-7/8" trailer ball for towing a small trailer, a clevis pin that accepts a tow hook or lunette ring for straight towing and a 5/8" hole for coupling a pin-style coupler. With its 2" x 2" shank, the 3-in-1 ATV ball mount lets you get more done no matter what your project may be. The included adapter bolts onto the ATV tongue using the included hardware and provides a 2" x 2" receiver tube opening to accept a ball mount shank or some other towing accessory. It also has a strap ring welded right onto its frame, providing a solid attachment point for a tow strap or rope. Material: Carbon Steel.
