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 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 distribution boards, mass transportation, and telecommunications. The markers are available in the international, resistance color code and in yellow with black printing 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 installation tool.
