Wire marking labels attach quickly and firmly to the wire for clear, concise wire identification. Slim, lightweight, pocket-sized wire marker books are easy to carry and contain a large selection of labels with numbers, letters, and special symbols. Write on wire labels and cable markers allow easy customization. Clip sleeve wire markers easily snap onto the wire and won't slip, slide, or fall off. Quickly identify voltages and power sources with conduit identification and voltage markers. These highly visible labels can be easily applied to busways, conduit, fuse boxes, switches, and other electrical equipment. Metal indenting machines let you create custom labels that are permanently stamped into a metal marker plate.
