Tri-Ball Trailer Coupler Lock
A tri-ball trailer hitch coupler lock has three differently sized ball substitute members. A lanyard extends in two directions off a portion which adjoins the ball substitute members, with mating portions of a lock permanently attached to each free end of the lanyard. One portion of the lock terminates in a pin sized to fit in the latch pin opening of the coupler, and the other portion of the lock is matably lockable onto the pin after the pin has been extended through the coupler pin opening. The lanyard preferably passes through an opening in the adjoinment portion offset from the center.
