Helagrip markers are used to label wires and cables before they are connected. The inner profile allows one size of marker to be used for multiple wire diameters. The arrow-shaped design prevents the markers from twisting relative to each other, making it much easier to read multi-character labels. The material's flexibility ensures good adhesion of the markers to the wire. Ideal for use in the assembly of control panels and distribution boards, mass transportation, and telecommunications. The markers are available as standard in the international, resistance color code, as well as in yellow with black print. Standard signs 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 TJC installation tool.
