Cable marker rings InLine 4 mm, numbers 0–9, 100 pcs, white

InLine cable marker rings with a 4 mm bore are a set of 100 white plastic numeric markers (numbers 0–9) designed for compact, sequential identification of small-diameter cables and wires. These pre-numbered rings slip onto already assembled cables and retain clear numeric labels to simplify wiring, maintenance and verification tasks in electrical installations and control panels.

Advantages

The marker rings provide compact, durable numeric identification in a standardized 4 mm bore size that fits many small cables. Their pre-printed numbers 0–9 enable fast sequential marking without the need for printing or handwriting. Made of plastic, they resist common handling during installation and remain visible in bundled conductors and tight spaces. Supplied as a set of 100, they support repeated use across multiple circuits or devices and reduce the time required for cable tracing and documentation.

Suitable for

• Numbering assembled small-diameter power and signal cables
• Identification of individual conductors within cable bundles and harnesses
• Labeling wires in control panels, distribution boxes and junctions
• Maintenance and testing workflows requiring quick numerical reference

Key specifications

• Bore diameter: 4 mm
• Quantity per set: 100 pieces
• Color: white
• Printed range: digits 0–9
• Material: plastic

How to use

Slide the appropriate numbered ring onto the cable by threading the cable through the 4 mm bore until the marker is in the required position. For sequential numbering, select rings in ascending order and push them into place so the printed digit faces outward for clear visibility. Use on cables already assembled into systems; the rings are intended to be fitted after connectors and terminations are installed, where the 4 mm bore accommodates most small conductor diameters.

Recommendations

For best results, choose the ring number sequence before installation to avoid rework. Ensure the cable diameter is compatible with the 4 mm bore to prevent loose fit or damage. Store unused markers in a dry place away from direct sunlight to maintain print legibility and plastic integrity.
