Helagrip markers are used for labeling cables and wires before their connection. The inner profile allows for the use of one marker size for several different wire diameters. The arrow-shaped design prevents the markers from twisting relative 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. These markers are ideal for use in control panel assembly, distribution panels, mass transportation, and telecommunications. Standard markers are available in an international, resistance color code or in yellow with black print. Standard characters include numbers (0-9), letters (A-Z), and standard electrical symbols. Other symbols are available upon request. For smaller diameters, we recommend using either the AD applicator or the TJC installation tool.
