Helagrip markers are used for labeling wires and cables before their connection. The internal profile allows for one marker size 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 the 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 as standard in an international, resistance color code, as well as in yellow with black print. 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.
