If you own multiple trailers or frequently tow a variety of loads, you know how much time and money are spent tailoring your towing system to each and every individual trailer.

This replacement head for the CURT adjustable tri-ball mount #45799 features three different trailer ball sizes to accommodate all standard coupler sizes: 1 7/8″, 2″ and 2 5/16″.
