Helagrip markers are used to label wires and cables before their connection. The internal profile allows the use of one marker size for several different wire diameters. The arrow-shaped design prevents the markers from rotating relative to each other, making it much easier to read multi-character labels. The material's flexibility ensures good adhesion of the markers to the wire. They are ideal for use in the installation of control panels and switchboards, mass transport, and telecommunications. The markers are available as standard in an international, resistance color code, as well as in yellow with black printing. 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 installation tool.
