Helagrip markers are used to label cables and wires before connecting them. The internal profile allows for one size of markers to be used for multiple different wire diameters. The arrow-shaped design prevents the markers from twisting, making it 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 panel installation, mass transportation, and telecommunications. Markers are available in international, resistance color codes and yellow with black print as standard. Standard symbols include numbers (0-9), letters (A-Z), and standard electrical symbols. Other symbols are available upon request. For smaller diameters, we recommend using the AD applicator or TJC installation tool.
