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 the markers from twisting relative to each other, making it easier to read multi-character markings. 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 as standard in an international, resistive color code, as well as in yellow with black print. Standard characters 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 the TJC mounting tool.
