The K-50 Sectional Machine from RIDGID is designed to clean 3/4 to 4-inch drainlines, making it an all-around sink, shower and floor drain-cleaning machine. Equipped with a 300-watt motor, it weighs less than 40 pounds, making it compact and versatile for professional use. It has an easy-to-use, instant-acting cable clutch to maximize operator control. Pull the handle down and cable spins at 400 rpm; release the handle and the cable stops instantly. It uses sections of 5/8-inch cable to clean 1 1/4- to 4-inch lines up to 100 feet. When equipped with an A-17 adapter, the machine can run 50 feet of 5/16-inch cable or 35 feet of 3/8-inch continuous-length cable. It is approved by CSA and UL standards, and includes an A-1 drain-cleaning mitt. 800/769-7743; www.ridgid.com.
