The Vevor sectional drain cleaning cable is designed for professional drain clearing in pipes from 0.8" to 3.9" in diameter. Its hollow-core spring steel construction provides flexibility, high tensile strength, and resistance to tangling and breakage. The 66' cable is built to navigate multiple 90° bends while handling tough blockages in sinks, toilets, and floor drains. A female slotted end allows easy installation with compatible blade holders, and the included 7 cutters add versatility for different clog types. It is compatible with Vevor 5/8" sectional drain cleaners and other 5/8" sectional drain cleaner machines.
