The Ridgid Power Spin+ Drain Cleaner features a kink resistant MaxCore cable designed for drill powered operation up to 500 RPMs. The Autofeed Trigger Technology allows the cable to self feed down the drain. The cable is positively retained in the drum to prevent cable pullout. Cleans drain lines from 3/4" to 1-1/2" in diameter. Simply pull the trigger and turn the drum for a clean drain with no mess.
