Helagrip markers are used to mark wires and cables before their connection. The internal profile allows the use of one marker size for several different wire diameters. The special arrow-shaped design prevents markers from twisting relative 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 transport, and telecommunications. Markers are available as standard in an international, resistance-based color code, as well as in yellow with black printing. Standard available characters 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.
