A ball mount is a towing accessory used to connect a trailer to a vehicle. It consists of a metal bar with a hitch ball attached at one end, allowing the trailer to pivot while being towed. Ball mounts come in various sizes and weight capacities to accommodate different types of trailers, such as utility trailers or boat trailers. To use a ball mount, it is inserted into the receiver hitch of a vehicle and secured with a pin. Proper selection of a ball mount is crucial for safe towing, as it ensures the trailer remains level and stable during transport.
