The Adjustable Trailer Hitch Tri-Ball Mount is a receiver hitch accessory consisting of three trailer hitch balls and a shank. The three hitch balls eliminate the need to remove and install different hitch balls or ball mounts. The adjustable ball mount allows you to use in the drop or rise position and also includes twist and lock ball mount push pins and a dual barrel lock with single key security to secure the hitch balls and ball mount in place. Made of lightweight, rust-proof anodized aluminum that offers superior protection from scratches and abrasions. This ball mount features increased towing capacity for today's towing demands, depending on your requirement. It is ideal for every day towing, but allows for maximum flexibility when towing multiple trailers and heavy cargo. Class V mounts are great for towing very large campers, large boats and yachts, and trailers carrying commercial construction equipment. While these are common uses for this class, it is important that you know the total weight of the trailer and its contents, and that you do not exceed the recommended maximum towing capacity determined by your vehicle manufacturer.
