Helagrip markers are used to mark wires and cables before connecting them. The inner profile allows one size of markers to be used for several different wire diameters. The special arrow-shaped design prevents markers from twisting relative to each other, which greatly facilitates the reading of multi-character markings. The material's flexibility ensures good adhesion of markers to the wire. Ideal for use in the installation of control panels and switchgear, mass transport, and telecommunications. The markers are available as standard in an international, resistive color code, as well as in yellow with black printing. Standard symbols 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.
