Helagrip markers are used to label wires and cables before connecting them. The internal profile allows one size marker to be used for several different wire diameters. The special 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 that the markers adhere well to the wire. Ideal for use in control panel and distribution box installation, mass transport, and telecommunications. The markers are available as standard in an international, resistance color code, as well as in yellow with black print. Standard characters 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 installation tool.
