Helagrip markers are used to label wires and cables before they are connected. The internal profile allows for one size marker to be used for several different wire diameters. The arrow-shaped construction prevents the markers from rotating relative to each other, making it easier to read multi-character labels. The material's flexibility ensures good adhesion of the markers to the wire. Ideal for use in control panel and switchgear assembly, mass transportation, and telecommunications. Standard markers are available 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 upon request. For smaller diameters, we recommend using the AD applicator or TJC mounting tool.
