Helagrip markers are used to label wires and cables before connecting them. The inner profile allows for 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 labeling. 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. The markers are available as standard in an international, resistance color code, as well as in yellow with black printing. 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.
