The RIDGID K-3800 Drum Machine is designed for cleaning indoor drains. Easy to transport, it requires minimal setup to clean sink lines, floor drains and roof vents. The cable spins at 240 rpm and fits 3/4- to 4-inch lines. Maximum drum capacity is 100 feet of 3/8-inch cable or 90 feet of 1/2-inch continuous-length cable. The corrosion-resistant molded cable drum won’t dent or rust. The drum adjusts for proper cable feed angle while the inner drum guards against cable flip-over. An optional sink drum holds up to 50 feet of 5/16- or 1/4-inch cable for cleaning 3/4- through 1 1/2-inch sink traps. The quick-release handholds allow easy cable change and transport. 800/769-7743; www.ridgid.com.
