Why Choose the Cembre 4390308 RMS-04 Cable Marker?
The Cembre 4390308 is a yellow RMS-04 push-on cable marker designed for permanent identification of electrical cables and conductors. Also identified by the manufacturer part number 59844-O, this marker is pre-printed with the letter O, making it ideal for alphanumeric wire identification in industrial control panels, switchgear, machinery and power distribution systems.
Manufactured from flexible soft PVC, the marker slides easily onto the conductor while providing a secure fit without adhesives or additional fixing accessories. Its push-on design enables rapid installation, while the chevron-cut profile ensures adjacent markers align neatly when creating multi-character cable identification sequences.
The RMS-04 size is designed for cables with a cross-sectional area of approximately 16–70 mm² and an outside diameter of 8–16 mm. The bright yellow body with a durable hot-pressed black embossed letter provides excellent visibility, helping electricians and maintenance engineers identify circuits quickly during installation, testing and servicing.
