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 special arrow-shaped construction prevents the markers from twisting relative to each other, making it much easier to read multi-character markings. The material's flexibility ensures good adhesion of the markers to the wire. Ideal for use in the installation of control panels and switchgear, mass transportation, and telecommunications. The markers are available in the international, resistance-coded color code, as well as in yellow with black printing. The standard symbols 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 mounting tool.
