Helagrip markers are used to label cables and wires before they are connected. The internal profile allows for the use of one marker size for several different wire diameters. The special arrow-shaped design prevents the markers from twisting, making it much 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 panel assembly, mass transportation, and telecommunications. Standard markers are available in an international, resistance color code as well as yellow with black printing. 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 the TJC mounting tool.
