Helagrip markers are used to label wires and cables before connecting them. The internal profile allows one marker size to be used for several different wire diameters. The arrow-shaped design prevents the markers from twisting relative to each other, making it much easier to read multi-character markings. The material's flexibility ensures good adhesion of the markers to the wire. Ideal for use in the installation of control panels and switchgear, mass transportation, and telecommunications. The markers are available as standard in an international, resistive color code and 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.
