The RIDGID 1/4 in. x 30 ft. Replacement Drain Cleaning Cable is designed to be used with the RIDGID K-30 Auto-Clean Drain Cleaner Machine. It spins a drain cleaning tool to break and remove tough clogs from pipes. Built for strength, the inner core cable is rugged and kink resistant to provide good flexibility and more cleaning power to the cable end. The ends of this drain snake cable have an interlocked tip so that either another section of cable or an auger head can easily be attached, without the need for tools, depending on the requirements of the job. Drain snake cable is easy to install and replaces kinked, cracked, or old cable.
