Helagrip markers are used to mark wires and cables before connecting them. The inner profile allows one size of markers to be used for multiple different wire diameters. The special arrow-shaped design prevents the markers from twisting in relation to each other, making it much easier to read multi-character markings. 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 transportation, and telecommunications. The markers are available as standard in an international, resistive color code, as well as in yellow with black printing. Standard signs include numbers (0-9), letters (A-Z), and standard electrical symbols. Other symbols are available on request. For smaller diameters, we recommend using the AD applicator or the TJC installation tool.
