Nothing is worst than hauling around that precious trailer load of cargo only to have vagrants hitch it up and ride off with your property when you aren't looking! Go Tow presents their solution to an age old problem, the universal coupler lock. This easy to use lock simply blocks the area the ball hitch would go so it is no longer possible for thieves to simply hook up and go. It is designed to fit 1-7/8", 2”, and 2-5/16" couplers. Made of heavy duty steel construction means it is perfect for everyday use or even for locking up a trailer that is in long term storage.
