Why Choose the Cembre 4421384 SM-09 Snap-On Cable Marker?
The Cembre 4421384 is a durable SM-09 snap-on cable marker designed for clear and reliable identification of electrical wires and cables. Also referenced as Cembre 17440-C, this yellow marker is permanently printed with the character “C”, making it suitable for structured cable identification in control panels, switchgear and industrial wiring systems.
Manufactured from a robust copolymer material, the marker provides excellent mechanical and physical performance in demanding electrical environments. Its resilient construction helps prevent deformation and deterioration during normal installation and service, supporting long-lasting and legible wire identification.
The SM-09 marker clips directly onto compatible cables without adhesives or specialist printing equipment. It is suitable for conductor sizes of approximately 1.5–2.5 mm², corresponding to around 15–13 AWG, and is supplied in a pack of 300 markers for efficient installation and maintenance work.

Clear and Reliable Electrical Cable Identification
Accurate cable identification helps electricians and maintenance engineers trace circuits, complete testing and diagnose faults more efficiently. The Cembre SM-09 system provides a simple way to apply permanent alphanumeric markings to individual conductors without using printers, adhesives or additional label holders.
The marker is attached directly to the cable using its snap-on profile. Once installed, the contrasting black character remains easy to read against the yellow background, while the double-sided print improves visibility when cables are installed inside crowded enclosures or wiring ducts.
