RIDGID drum machines — the K-400, K-750, K-1500, and K-7500 — for clearing 2" through 10" main drains, building sewers, and storm lines.
RIDGID drum machines are the production tools of the drain cleaning trade. The K-7500 with 5/8" or 3/4" cable clears full-diameter blockages in 8" main lines. The K-750 covers 4" and 6" sewers and laterals where most residential and small-commercial work happens. AUTOFEED, integrated foot pedals, and pneumatic clutches mean operators spend the day cleaning drains, not fighting the machine.
