Reese Towpower 21512 Tri-Ball Trailer Hitch Ball Mount, (1-7/8 Inch, 2 Inch, 2-5/16 Inch Trailer Hitch Balls), Fits 2 Inch Square Receiver, 10,000 lbs. Capacity, Black

If you tow, you know that trailer couplers come in several sizes, which means you may need a different hitch ball for each trailer you plan to pull. REESE's high-capacity rugged tri-ball hitch attachments are uniquely designed to tackle heavier, bulkier towing needs while also giving you the greatest convenience and versatility in towing. They come with 3 different sized hitch balls and towing capacities, a steel design, and a straight steel shaft that fits any 2 in. receiver, all protected with a black powder coat finish to resist rust and corrosion. Just rotate the ball mount to the hitch ball that best fits the coupler of the trailer you are towing. Then hook up your trailer and head out. It’s that easy!
