A ball mount is a towing accessory used to connect a trailer to a vehicle. It consists of a metal platform with a spherical ball on top, allowing the trailer's coupler to attach securely. Ball mounts come in various sizes and weight capacities to accommodate different trailers and towing needs. To use a ball mount, it is inserted into the receiver hitch of a vehicle and secured with a pin. Proper selection of the ball mount is crucial for safe towing, as it must match the trailer's weight and height requirements. This ensures stability and prevents accidents during transport.
