Helagrip markers are used for marking wires and cables before their connection. The inner profile allows for the use of one size of markers for several different wire diameters. The special arrow-shaped design prevents the markers from rotating relative to each other, making it much easier to read multi-character markings. The material's flexibility ensures good adherence of the markers to the wire. Ideal for use in the assembly of control panels and switchgear, mass transport, and telecommunications. The markers are available as standard in an international, resistance color code and in yellow with black print. Standard available characters include numbers (0-9), letters (A-Z), and standard electrical symbols. Other symbols are available to order. For smaller diameters, we recommend using the AD applicator or the TJC installation tool.
