Helagrip markers are used to label wires and cables before they are connected. The internal profile allows one size of marker to be used for several different wire diameters. The arrow-shaped design prevents markers from twisting relative to each other, making it much easier to read multi-character markings. The material's flexibility ensures a good grip on the wire. Ideal for use in the installation of control panels and switchboards, mass transportation, and telecommunications. The markers are available in the international, resistive color code and in yellow with black printing. Standard signs 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 installation tool.
