The B & W 8" Tow & Stow Tri-Ball Hitch features three separate ball sizes in 1-7/8", 2" & 2-5/16", eliminating the need for multiple ball mounts. To use, rotate the ball to the size needed for towing, then adjust the height in one-inch increments. The ball mount can be stowed under the hitch when not in use. This class IV Tri-Ball Hitch has a chrome finish with an adjustable 5" drop & 5-1/2" rise. It has towing capacity of 1,000 lb tongue weight and 10,000 lb trailer weight.
