Helagrip markers are used to label wires and cables before connecting them. The internal profile allows for the use of one size of markers on several different wire diameters. The arrow-shaped design prevents the markers from twisting in relation to each other, making it much easier to read multi-character labels. The material's flexibility ensures a good grip of the markers on the wire. Ideal for use in the installation of control panels and switchgear, mass transport, and telecommunications. The markers are available as standard in an international, resistance-coded color code or in yellow with black print. 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 the TJC installation tool.
