Helagrip markers are used to label wires and cables before their connection. The inner profile allows for one size of markers 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 multicharacter markings. The material's flexibility ensures good adhesion of the markers to the wire. Ideal for use in the assembly 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 print. 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 installation tool.
