Helagrip markers are used to label wires and cables before their connection. The internal profile allows one marker size to be used for multiple wire diameters. The special arrow-shaped design prevents markers from twisting relative to each other, which greatly facilitates reading of multi-character markings. The material's flexibility ensures good adhesion of markers to wires. Ideal for use in control panel and distribution board installation, mass transportation, and telecommunications. Markers are available as standard in international, resistance color codes, as well as 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.
