Wire markers and cable markers attach to wires and cables. They permit component identification and improve maintenance, traceability, and security. Many different types of wire markers and cable markers are available. Basic wire marker and cable marker categories include labels, sleeves and tags. Specialized products include laser wire markers, insert markers, tie-on cable markers, hot stamp markers, number kits, heat shrinkable sleeves, shrink-tag markers, cable identification marker plates, flex-tag wire markers, and rip tags. Wire marker and cable marker suppliers are located across the United States and around the world. They comply with a variety of safety and quality standards from organizations such as the Society of Automotive Engineers (SAE), Underwriters Laboratories (UL), and the Canadian Standards Association (CSA). Wire and cable markers that meet U.S. military standards feature a MIL-SPEC, MIL-STD, or MIL-DTL designation.
