Kit comes complete with over 8' of custom 240 lb. test black nylon seine twine, a 100% stainless steel crane swivel with a load rating of 411 lbs., and a heavy duty coast lock terminal end. The gunmetal black crane swivel is three times stronger then a brass swivel. Attach the downrigger line directly to the crane swivel and the swivel becomes the stopper bead for the auto stop feature. Ensures that your downrigger ball will stop short of the pulley every time.
