Helagrip markers are used for labeling cables and wires before they are connected. The internal profile allows for 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 material's flexibility ensures that the markers adhere well to the wire. They are ideal for use in control panel and switchboard installations, mass transport, and telecommunications. The markers are available in the international, resistance color code as well as 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 mounting tool.
