What Is a Trailer Ball?
Also known as a trailer hitch ball, it is one component in a system designed to connect a trailer to a towing vehicle. The trailer ball is bolted to the ball mount, which is in turn connected to the trailer hitch, the device that is securely attached to the towing vehicle. The ball itself provides the means to attach the coupling of a trailer so that it can be maneuvered through a variety of different angles when in motion. The ball effectively allows the caravan or trailer to turn freely as needed.
