Clear even the toughest blockages with this Ridgid K-40 Sink Machine (71702). It features a kink-resistant, compression-wound inner core cable. The two-piece “twist lock” drum housing will not dent or corrode, and gives you easy access to the inner drum and cable. The design of the inner drum virtually eliminates cable flip-over inside the drum. This particular sink machine also includes a pair of drain cleaning gloves.
