Use these RS PRO blank cable marker sleeves for labelling electrical wires prior to installation. You can mark multiple labels with a laser printer and then apply them to cables using a heat gun.

The sleeves are made of flame retardant polyolefin, so they won't easily catch fire if there's an electrical fault. It's easy to tear off each sleeve as needed, as they're supplied pre-cut with a dotted line.


These components meet UL 224 (Underwriters Laboratories) standards for safety extruding insulating tubing, meaning they're safe to use in the insulation of electrical wiring. Heat shrink sleeves such as these have good chemical and abrasion resistance, so they're suitable for use in demanding industrial environments.
