    Comments about Master Lock Trailer Lock Kit:

    I bought this to secure a 18 ft utility trailer I use to haul tractors. I was awakened one day when a theif busted this off. Luckily my shotgun persuaded them to give up. This thing is very easily defeated with any small striking object. Get yourself a better coupler lock. Especially if you use a good quality bulldog hitch, this will not lock down right.
