Helagrip markers are used to label wires and cables before they are connected. The internal profile allows for one size of marker to be used for multiple different wire diameters. The arrow-shaped design prevents markers from twisting in relation to each other, making it easier to read multi-character labels. The material's flexibility ensures that the markers adhere well to the wire. They are ideal for use in control panel and distribution board assembly, mass transportation, and telecommunications. The markers are available in the international, resistance color code, as well as 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 mounting tool.
