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 markers from twisting relative to each other, making it easier to read multi-character labels. The material's flexibility ensures that the markers adhere well to the wire. Ideal for use in control panel and distribution board assembly, mass transportation, and telecommunications. Markers are available as standard in an international, resistance-coded color scheme and in yellow with black printing. Standard characters 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.
