These blank cable marker sleeves from RS PRO allow you to label electrical wires before they're put to use. You can use a laser printer to mark multiple labels and then affix them to your cables using a heat gun.


The sleeves are made of high-quality, flame retardant polyolefin, meaning they won't easily catch fire if there's an electrical fault. The cable markers are also pre-cut, so you can easily tear them off as needed.


Heat shrink sleeves of this type are suitable for use in workshops and factories thanks to their good chemical and abrasion resistance. They're rated UL 224 by Underwriters Laboratories, meaning they're safe to use in electrical wiring insulation.
