Helagrip markers are used to label cables and wires before their connection. The internal profile allows for the use of one marker size for several different 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 a good fit of the markers to the wire. Ideal for use in control panel and switchboard assembly, mass transportation, and telecommunications. Markers are available in international, resistance color codes and in yellow with black print as standard. Standard symbols include numbers (0-9), letters (A-Z), and standard electrical symbols. Other symbols are available on request. For smaller diameters, we recommend using the AD applicator or TJC mounting tool.
