Helagrip markers are used to label wires and cables before connecting them. The internal profile allows one size of markers to be used for several different wire diameters. The special arrow-shaped design prevents markers from twisting, making it much easier to read multi-character labels. The material's flexibility ensures good adhesion of the markers to the wire. Ideal for use in control panel and distribution board installation, mass transportation, and telecommunications. The markers are available in the international, resistance color code and in yellow with black print as standard. Standard symbols include numbers (0-9), letters (A-Z), and standard electrical symbols. Other symbols are available on request. For smaller diameters, we recommend using the AD applicator or TJC mounting tool.
