Cable Specifications

The Ridgid 56787 is a 5/16 inch by 25 foot IC drain cleaning cable made of steel with an inner core and drop head auger end. It fits K-25, K-3800, K-40, K-40AF, K-45 and K-45AF drum machines, hand spinners and sink machines. Professional plumbers and maintenance crews use it to clear blockages in sewer pipes.

Diameter Range

This cable handles drain lines with an inside diameter between 3/4 inch and 1 1/2 inch. The 5/16 inch cable diameter and 25 foot length determine which pipes it can enter and how far it reaches. Selecting the correct diameter is the single specification that decides whether this is the right part for the job.

Capacity and Headroom

The 25 foot length provides reach for typical residential and light commercial runs within the 3/4 to 1 1/2 inch range. The steel inner core construction transmits torque to the drop head auger for breaking up obstructions. It runs out on lines larger than 1 1/2 inch or runs exceeding 25 feet, and it is not suited for smaller diameters below 3/4 inch.

Questions about this item

How does the 25 ft length and 5/16 in diameter perform in a real drain line?

The 25 ft steel cable with inner core reaches deep into lines from 3/4 in to 1 1/2 in ID, while the drop head auger end navigates bends and breaks up blockages in sink and sewer pipes.

Which machines does the IC cable standard fit, and what does that limit?

This IC cable fits Ridgid K-25, K-40, K-40AF, K-45, K-45AF, and K-3800 drum machines, drain guns, and hand spinners, so it is limited to those specific compatible series.

What physical clearance and mounting does the 5/16 in drum cable need?

The 5/16 in diameter drum cable mounts directly into compatible Ridgid drum machines and requires a drain line with at least 3/4 in inside diameter to feed and rotate properly.
