Prevent unauthorized hook-ups! Made from a solid cast ductile cast-iron steel alloy, this single-component design is incredibly strong. The lock is extremely user-friendly thanks to its one-piece construction, right down to the convenient carrying handle. The carrying handle prevents accidental locking when stored in the ready-to-use position. Locks without a key; unlocks with a key. Two keys included. Only 1 of 360 million keyed combinations will open it. Additional keys are available by special order only. Fits all standard trailer king pins. Made in the USA. Sold individually.
