Ridgid Tool's K-45 manual and K-45AF autofeed drain cleaning machines are designed for 3/4" to 2-1/2" inch drain lines and are ideal for sinks, bath tubs and showers. Cable is offered in three sizes - 1/4", 5/16" and 3/8" - and in lengths of up to 5'. The K-45AF features two-way autofeed, allowing operators to clean drains better and faster, quickly working back and forth through drain blockages. Both drain cleaners have variable speed operation from 0 to 600 rpm. The inner drum prevents leakage to reduce on-site cleaning and clean-up times. A compression-wound inner core cable combines strength and flexibility to avoid kinking.
