Helagrip markers are used to label cables and wires before their connection. The inner profile allows for the use of one marker size for several different wire diameters. The arrow-shaped design prevents markers from twisting relative to each other, making it easier to read multi-character markings. The material's flexibility ensures good adhesion of the markers to the wire. Ideal for use in the assembly of control panels and switchboards, mass transportation, and telecommunications. Markers are available as standard in an international, resistance color code, as well as in yellow with black print. Standard available characters 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.
