Helagrip markers are used to label wires and cables before connecting them. The internal profile allows for one marker size to be used for multiple wire diameters. The arrow-shaped design prevents the markers from twisting, making it easier to read multi-character labels. The material's flexibility ensures good adherence to the wire. Ideal for use in control panel and distribution board assembly, mass transport, and telecommunications. Markers are available in international resistance color code and in yellow with black printing. Standard symbols include numbers (0-9), letters (A-Z), and common electrical symbols. Other symbols are available upon request. For smaller diameters, we recommend using the AD applicator or TJC installation tool.
