About Split Loom Tube

Split loom tube (also called split conduit, wire loom, tidy loom, or cable sleeve) is a corrugated flexible tube with a longitudinal split running the full length — allowing cables and wire harnesses to be inserted sideways into the tube without disconnecting the ends. The split closes over the cables under the natural tension of the tube wall, holding the cables neatly inside while providing protection from abrasion, chafing, heat, and environmental contamination.

Split loom is widely used in automotive, marine, caravan, industrial, and electrical wiring applications where cables need to be bundled, protected, and routed neatly — and where the ability to add or remove cables without cutting or disconnecting is important. The polypropylene material provides chemical resistance to the oils, fluids, and solvents commonly encountered in automotive and marine environments.

The CST20 suits large cable bundles — with a 21.1mm inner diameter it accommodates substantial multi-cable harnesses common in automotive, marine, and industrial main wiring runs. A 30m bulk roll version is also available as the CST20/30. It is manufactured in Australia and sold as a 10m roll.

Q: What is the inner diameter of the CST20?
A: The CST20 has a 21.1mm inner diameter — the available space for cables inside the tube.

Q: How is split loom installed?
A: The split loom is flexed open along the longitudinal split and cables are pushed in sideways. No disconnecting of cable ends is required. The tube naturally closes over the cables.

Q: Is the CST20 suitable for automotive use?
A: Yes — polypropylene construction provides chemical resistance to automotive oils, fluids, and solvents. The FMVSS302 flammability pass confirms suitability for automotive wiring applications.

Q: How long is the roll?
A: The CST20 is sold as a 10m roll.
