Helagrip markers are used to label wires and cables before their connection. The internal profile allows for the use of one marker size for several different wire diameters. The arrow-shaped design prevents the markers from twisting, making it easier to read multi-character markings. The material's flexibility ensures good adhesion of the markers to the wire. They are ideal for use in control panel and switchboard assembly, mass transportation, and telecommunications. The markers are available in the international, resistance color code, as well as in yellow with black print. 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.
