Helagrip markers are used to label wires and cables before they are connected. The internal profile allows for one marker size to be used for several different wire diameters. The arrow-shaped design prevents the markers from twisting 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. Ideal for use in control panels and switchgear assembly, mass transportation, and telecommunications. The markers are available as standard in an international, resistance color code and 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 marker applicator or TJC installation tool.
