From Monroeville, Ohio, Jones Manufacturing makes American-made LockJaw tool racks and J-Lock load-lock holders for trucks, trailers, and other equipment. Its LockJaw line organizes long-handled tools while the original J-Lock system provides lockable, anti-theft storage and is supplied as a factory-installed option by major truck manufacturers. Jones also makes the Ball Hooker, a rolled-steel towing plate designed for ball-hitch-equipped vehicles.
