Ball Mount features two or three trailer balls mounted onto a straight shank to accommodate various coupler sizes and loads. Features a 1 7/8", a 2" and a 2 5/16" ball. The 1 7/8" trailer ball can tow up 5, 000 lbs. of gross trailer weight and 500 lbs. of tongue weight. The 2" ball can handle 7, 500 lbs. of GTW and 750 lbs. of TW, and the 2 5/16" ball accepts loads up to 10, 000 lbs. with 1, 000 lbs. of TW. This multipurpose ball mount also features a dual-length option and has a solid shank for increased strength. All of our multi-use ball mounts come with a gloss black powder coat finish and a 2" x 2" shank. The multiple-ball design allows for quick changes between ball sizes without needing to install or own an entirely different ball mount. Because the balls are permanently welded to the shank, these ball mounts are also very secure, eliminating the possibility of a ball coming loose and deterring any potential theft.
