The Pin Lock from American Fifth Wheel Safety Systems is designed to offer peace-of-mind while towing a fiver. Once Pin Lock is in place, the only way the fifth-wheel could be completely disconnected would be to raise the king pin over the lock system, according to the company. Pin Lock can be used with select tabletop design hitches, including various models from RBW.
