Helagrip markers are used to label wires and cables before they are connected. The internal profile allows one size of marker to be used for multiple wire diameters. The arrow-shaped design of the markers prevents them from twisting in relation to each other, making it much easier to read multi-character labels. The material's flexibility ensures that the markers adhere well to the wire. They are ideal for use in control panel and switchboard assembly, mass transportation, and telecommunications. The markers are available as standard in an international, resistor color code and in yellow with black printing. 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 installation tool.
