| Patented Hollow Shaft Cable Swivel Tool The CST slides on a 3/8" stretched cable (not supplied) and is moved along by jet reaction or by using a pulling cable. The rotation is powered by an air motor. It has a versatile 6-port head with varying angles including one that allows the tool to travel by itself. Simply select the ports you want to use and plug the others. The ports include 2 @ 90˚, 2 @ 80˚, 1 @ 70˚ and 1 @ 110˚. Extension nipples further adapt the tool to various vessel sizes and improve jet quality by reducing stand-off distance.
