Gooseneck Coupler LockHeavy-duty cast aluminum lock fits the on the bottom of most gooseneck couplers, creating a barrier that does not allow a ball to be inserted. Fits most, including Stallion, T.E.M., Superior, and Hammer blow. Has a 3/4" pin for a secure fit. The pin has a hole at the end & must have a lock inserted in the pin, in order to secure the coupler lock. The coupler can still be dropped when locked, unless you have a gooseneck STEM BOLT lock on the upper adjustment pin (as shown). We recommend both lock be used together for the proper determent for thieves.
GNSL (stem bolt lock) and RTP70 (round padlock), each sold separately.
