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, making it much easier to read multi-character labels. The flexibility of the material ensures that the markers adhere well to the wire. Ideal for use in the assembly of control panels and switchgear, mass transportation, and telecommunications. Markers are available as standard in an international, resistance-coded color code and in yellow with black print. Standard available 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.
