Helagrip markers are used to label wires and cables before connecting them. The internal profile allows for one marker size to be used for multiple different wire diameters. The special arrow-shaped design prevents markers from twisting relative to each other, making it much easier to read multi-character labels. The flexibility of the material ensures that markers adhere well to the wire. Ideal for use in the assembly of control panels and distribution boards, in mass transportation, and in telecommunications. Markers are available as standard in an international, resistance color code and in yellow with black printing. Standard signs 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.
