HEAVY DUTY CONSTRUCTION - The solid steel cuff and kingpin lock are extremely difficult to defeat and engineered specifically for maximum tamper resistance. The forged locking pin is incredibly strong, and cannot be disengaged without the key to the lock. Each set includes a slide bolt lock and two keys.

STRONG DETERRENT - The last thing a trailer thief wants to see is a heavy duty Vulcan king pin lock. Once the would-be thief sees the lock they will almost always move on to an easier target.
