This set is application-specific for the B&W 3 in Tow & Stow 21K lb adjustable ball mount - it does not fit the 2 in or 2.5 in Tow & Stow 10K/18K models. It includes three hitch pin locks sized for the ball mount itself and one lock for the 3 in receiver, all keyed alike so one key works the whole set.
Confirm your ball mount is the 3 in, 21K lb Tow & Stow model before ordering - this set is not interchangeable with other Tow & Stow sizes.
