Helagrip markers are used to label cables and wires before connecting them. The inner profile allows for one marker size to be used for multiple different 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 the markers to the wire. Ideal for use in the assembly of control panels and switchboards, mass transport, and telecommunications. Standard markers are available in an international, resistance color code, as well as in yellow with black print. 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 mounting tool.
