Cable Diameter and Length

The Ridgid 56792 is a 5/16 in diameter steel drain cleaning cable that extends 35 ft. It is built for professional plumbers and maintenance crews who need a reliable inner‑core drum cable for clearing blockages in small‑to‑medium drain lines.

Sustained Load Behaviour

The inner‑core construction resists kinking and maintains torque transfer during extended runs through 3/4 in to 1‑1/2 in pipes. Its bulb auger end engages debris steadily without binding, allowing continuous rotation on compatible drum and sink machines.

Interface Limits

This cable fits K‑3800, K‑40, K‑40AF, K‑45 and K‑45AF series machines. It cannot be used on lines larger than 1‑1/2 in inside diameter or smaller than 3/4 in, and it is not compatible with sectional cable machines or larger drum units.

Questions about this item

How much heat or noise does the 5/16 in cable produce during extended drain cleaning jobs?

The steel cable itself generates no heat or noise; any sound or warmth comes from the compatible K-3800, K-40, K-40AF, K-45 or K-45AF machine driving it.

Which machine must I already own to run this 35 ft IC cable with bulb auger?

It fits Ridgid Drain Guns, Drum Machines and Sink Machines in the K-3800, K-40, K-40AF, K-45 and K-45AF series.

Will the 5/16 in diameter cable work in the older 3/4 in to 1-1/2 in drain lines I already service?

Yes, it is designed for lines from 3/4 in up to 1-1/2 in inside diameter.
