BOLT Coupler Pin Lock

BOLT coupler pin lock

BOLT Locks use specially crafted tumblers to memorize a vehicle’s ignition key the first time it is inserted into the lock.

One complete turn of the key moves the tumblers to fit that one specific key, resulting in a uniquely programmed lock. The stainless steel coupler pin lock fits couplers from ½-inch to 3 3/8 inches in 1/8-inch increments. BOLT’s coupler pin lock secures the locking lever from any movement and serves dual purposes: locking a trailer ball when hitched to a vehicle or making the coupler unusable when off the vehicle. When the trailer is not hitched to a vehicle, the coupler pin lock secures the locking lever so that it cannot be moved in order for a different vehicle to attach a ball mount to the trailer.
