Why Choose the Cembre 4439382 SNAP SM-21 Cable Marker?
The Cembre 4439382, also identified by manufacturer code 17980-MNS, is a durable SNAP SM-21 clip-on cable marker designed for clear and permanent identification of electrical cables in industrial installations. Manufactured by Cembre, this white marker is suitable for panel builders, electrical contractors and maintenance engineers who require reliable cable identification in control panels, switchgear and automation systems.
The marker uses Cembre’s practical SNAP installation system, allowing it to be fitted directly onto compatible cables without adhesive sleeves or separate marker holders. Its moulded symbol provides a clear identification point, while the robust polymer construction supports dependable performance across a wide operating temperature range.
Designed for cables with an outside diameter of approximately 11–15 mm and conductor cross-sections from 35–70 mm², the Cembre 4439382 is manufactured from halogen-free POM acetal resin. The white RAL 9003 finish provides strong visibility inside electrical panels, and the markers are supplied in packs of 50 pieces.
