General's Sink Drain Cleaners offer you a complete system for cleaning drain lines from 1-1/4" through 3" in diameter. They're built to clear clogged drains for a decade or more. Our Dyna-Thrust™ bearing system is one reason why. It helps carry the weight of the drum, significantly reducing wear on the motor shaft bearing and extending the life of the tool. Of course the cables are Flexicore® - with an integral wire rope center. With a variety of cables, cutters and accessories available, you have the right combination for any clogged drain problem.
