Drain Cleaner Spring Cable Specification Guide For Plumbing Distributors

The cable is the part of a drain auger that actually does the work, and it is the part distributors most often get wrong when specifying an import program. A cable that is too thick will not enter a small trap; one too thin will not shift a real blockage; the wrong head style leaves the job half-done. This guide explains the cable specifications TORCHMARK publishes for its drain-cleaner range so you can brief your factory contact and your buyers with precision.

The Two Numbers That Matter: Outer & Wire Diameter

Every drain-cleaner page in the catalog carries a cable specification table with two columns:

• Cable outer diameter (mm) — the overall thickness of the coiled cable. This decides which pipe and trap the auger will enter.

• Wire diameter (mm) — the thickness of the individual spring steel wire the cable is wound from. This decides how much force the cable transmits before it coils or kinks.

TORCHMARK builds these cables from heavy-duty carbon-steel spring wire. The exact outer/wire diameter is set per model, and the range is offered in multiple cable diameters so distributors can match the tool to the pipe sizes common in their market.

Buyer takeaway: do not import “a drain auger” — import a defined outer/wire diameter for the pipe sizes you sell into (e.g., 32–50 mm household drains vs. larger commercial lines).

Cable Length: The 5–15 m JQ-020 Series

The JQ-020 family is the catalog’s core coiled-cable drain cleaner:

• JQ-020A — 5–15 m cable length

• JQ-020B — 5–15 m cable length

• JQ-020C — 5–15 m cable length

The 5–15 m figure is the reach range, not a single fixed length — distributors specify the length their technicians need. Longer cable serves bigger buildings and longer runs; shorter cable keeps a residential van uncluttered.

Buyer takeaway: decide the length mix (short for vans, long for contract maintenance) before you commit volume.

Head Style: The Corkscrew

The working end of the cable is a corkscrew head that threads through blockages easily. Head style is offered in several variants so the same cable family suits different debris:

• Corkscrew for general soft blockages.

• Double worm screw (on the rod-set kit) for heavier, longer runs.

Buyer takeaway: confirm head style per SKU; a corkscrew head is the default for the coiled-cable models.

Housing & Drive

The cable runs in a high-impact, heavy-duty plastic housing, which keeps the tool light for the van and resistant to jobsite knocks. Two drive formats share the same cable family:

• Hand-operated — offset-crank or straight-handle.

• Drill-powered — power-drill attachment with scratch-resistant protective vinyl tubing.

The vinyl tubing matters: it protects pressed-steel and ceramic surfaces the cable passes near.

What To Put On The Specification Sheet

When you brief TORCHMARK for an import order, lock these fields:

Pinning these prevents the most common import mistake: receiving a tool that does not fit the pipe sizes your market actually has.

Pair The Cable With The Right Tool Type

Cable spec is only half the decision. Match the cable format to the tool:

• Coiled cable (JQ-020A/B/C) — hand and drill drain cleaners.

• Sectional rod (10 × 920 mm, ~9 m assembled) — rod-set machine for long runs.
