Helagrip markers are used for marking 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 much easier to read multi-character markings. The material's flexibility ensures a good grip of the markers on the wire. They are ideal for use in control panel and switchboard assembly, mass transportation, and telecommunications. Markers are available in the international, resistance color code, and in yellow with black printing as standard. Standard 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.
