Helagrip markers are used to label wires and cables before they are connected. The internal profile allows for one size of marker to be used for multiple wire diameters. The arrow-shaped design prevents the markers from twisting, making it easier to read multi-character labels. The material's flexibility ensures good adhesion of the markers to the wire. Ideal for use in control panels, distribution boards, mass transit, and telecommunications. The markers are available in the international, resistance color code and in yellow with black print as standard. Standard symbols 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 mounting tool.
