Helagrip markers are used to label cables and wires before their connection. The internal profile allows for the use of one size of markers 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 labels. The material's flexibility ensures good adhesion of the markers to the wire. Ideal for use in the installation of control panels and switchboards, mass transport, and telecommunications. Standard markers are available in an international, resistive 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 TJC installation tool.
