Helagrip markers are used to label wires and cables before connecting them. The internal profile allows one marker size to be used for multiple wire diameters. The arrow-shaped design prevents the markers from rotating relative to each other, 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 the assembly of control panels and switchboards, in mass transport, and in 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 the TJC installation tool.
