Helagrip markers are used to label cables and wires before they are connected. The internal profile allows the use of one marker size 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 labeling. The material's flexibility ensures a good fit of the markers to the wire. Ideal for use in control panel and switchgear assembly, mass transportation, and telecommunications. The markers are available as standard in an international, resistive color code and in yellow with black printing. 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 TJC installation tool.
