Helagrip markers are used to label wires and cables before their connection. The internal profile allows for one size of markers to be used for multiple different wire diameters. The arrow-shaped construction prevents the markers from twisting relative to each other, which significantly facilitates the reading of 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. The markers are available as standard in an international, resistance color code and in yellow with black printing. Standard available 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 installation tool.
