Helagrip markers are used to label wires and cables before connecting them. The inner 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 good adhesion of the markers to the wire. Ideal for use in control panel and distribution panel assembly, mass transportation, and telecommunications. The markers are available as standard in an international, resistance color code, and in yellow with black printing. 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.
