Helagrip markers are used to label wires and cables before their connection. The internal profile allows for the use of one marker size for several different wire diameters. The special arrow-shaped construction prevents the markers from twisting relative to each other, making it easier to read multi-character markings. The material's flexibility ensures good adhesion of the markers to the wire. Ideal for use in control panel and distribution board assembly, mass transportation, and telecommunications. The markers are available as standard in an international, resistance color code and 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 installation tool.
