Helagrip markers are used to label wires and cables before connecting them. The inner profile allows one size of markers to be used for several different wire diameters. The arrow-shaped design prevents the markers from twisting, making it easier to read the multi-character label. The material's flexibility ensures good adhesion of the markers to the wire. Ideal for use in control panel installation, distribution boards, mass transportation, and telecommunications. The markers are available in the international, resistance color code and yellow with black print as standard. 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.
