Helagrip markers are used to label wires and cables before they are connected. The internal profile allows 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 easier to read multi-character markings. The material's flexibility ensures that the markers adhere well to the wire. They are ideal for use in control panel and distribution box assembly, mass transportation, and telecommunications. The markers are available in the international, resistance-coded color code and in yellow with black printing. The standard symbols available are 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.
