Helagrip markers are used to label wires and cables before connecting them. The internal profile allows one size of markers to be used for several different wire diameters. The arrow-shaped design prevents the markers from twisting in relation to each other, making it much easier to read multi-character 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 transportation, and telecommunications. The markers are available as standard in an international, resistance-coded color scheme, as well as in yellow with black print. The standard symbols available are 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 the TJC installation tool.
