Helagrip markers are used to label wires and cables before connection. The internal profile allows for one marker size to be used for multiple 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 good adhesion of markers to the wire. Ideal for use in control panel and distribution panel assembly, mass transport and telecommunications. Markers are available as standard in the 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 by request. For smaller diameters, we recommend using the AD applicator or the TJC installation tool.
