<br /><br />Kagee they sell these in sizes from this one which is 1/2" to 3-3/8" long deadbolts (for couplers with surge brakes). I believe there is also an adjustable style. My guess is you could measure the size you would need and buy accordingly. Looks like 7/8", 2", and 2-1/2" spans as well. Might be worth looking into.<br /><br /><br />I am lucky enough that a small loop padlock will fit snugly enough to make bolt cutters relatively useless....but i will prolly switch to this.<br />
