Helagrip markers are used to label wires and cables before they are connected. The internal profile allows for one size of markers to be used for several different wire diameters. The arrow-shaped design prevents the markers from twisting relative to each other, making it much easier to read the multi-character label. The material's flexibility ensures that the markers adhere well to the wire. Ideal for use in control panel and switchboard assembly, mass transportation, and telecommunications. The markers are available as standard in an international, resistance color code and in yellow with black printing. 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.
