The TowSmart Adjustable Ball Mount is ideal for those with more than one trailer or tow vehicle. It features a hollow steel design providing you with ultimate strength when towing your cargo. The heavy-duty steel construction is extremely durable with a black powder coat finish that is corrosion resistant and provides superior protection from the outdoor elements. The ball mount adjusts from 7 ½” drop to 6 ¼” rise depending on your requirement when towing. It features a 2″ x 2″ shank with an impressive high towing capacity. It is important to know the total weight of the trailer (GTW) you are towing and the maximum towing capacity determined by the vehicle manufacturer.
