Helagrip markers are used to label wires and cables before connecting them. The inner profile allows one size marker 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 a good fit of the markers to the wire. Ideal for use in control panel installation, distribution boards, mass transport, and telecommunications. The markers are available as standard in an international, resistance color code, and in yellow with black print. 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 the TJC installation tool.
