Stick a tag on your wiring with this set of clip-on cable markers from HellermannTyton. They're pre-printed for quick identification of wires and lock together, aligning the text and resisting rotation. Snap-on fixing makes installing the tags on fibre cables by hand a breeze. Alternatively, slide and twist up to 20 markers in place at once using the special applicator tool (408-4917).

• Made from robust PA66 that's resistant to wear, impact and chemicals
• Halogen-free, so no toxic gases are released in the event of fire
• Stays securely locked to the wire, even under heavy vibrations

• Telecommunications networks
• Server rooms
• Marine engineering

Marking cables keeps them organised and makes them easier to identify, which is important in setups with large quantities of wiring such as data centres.
