Helagrip markers are used to label wires and cables before connecting them. The inner profile allows 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, which greatly facilitates reading of multi-character labels. The material's flexibility ensures good adhesion of the markers to the wire. Ideal for use in control panel and switchboard assembly, mass transportation, and telecommunications. Markers are available as standard in the 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 on request. For smaller diameters, we recommend using the AD applicator or TJC installation tool.
