Helagrip markers are used to mark cables and wires before their connection. The internal profile allows for one marker size to be used for several different wire diameters. The arrow-shaped design prevents markers from twisting, 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 box assembly, mass transportation, and telecommunications. Markers are available in the international, resistance color code as well as in yellow with black print. Standard symbols include numbers (0-9), letters (A-Z), and common electrical symbols. Other symbols are available upon request. For smaller diameters, we recommend using the AD applicator or the TJC installation tool.
