Curt has made things simple with the multi-ball mount with a tow hook. This all-in-one ball mount behemoth features three trailer balls with three different ball diameters and a tow hook for recovery towing. It allows you to easily accommodate multiple trailers and coupler sizes and fits any trailer hitch with a 2" x 2" receiver tube opening. For whatever trailer you are towing on any given day, the multi-ball mount makes it easy to hitch up and go. With three trailer balls on one shank, simply rotate the ball mount to the correct size ball, insert a hitch pin and you are ready to couple your trailer. There is no need to switch and store multiple ball mounts or to mount and torque different size trailer balls. The tow hook and all three trailer balls on the multi-ball mount are welded onto a solid steel shank, giving them a strong foundation and eliminating the possibility of coming loose or being stolen. With the added tow hook, the multi-ball mount is also the perfect accessory for recovering stuck vehicles or straight-line pulling various loads. The tow hook's capacity is limited to the trailer hitch's capacity. The Curt multi-ball mount comes with a durable black powder coat finish on the shank to help it withstand prolonged exposure to the elements, and it features two possible attachment lengths of 7" or 8-1/2".
