Wire number tube markers for cable identification and management. Durable plastic snapon markers are available in four conductor size options and in 100 or 150 piece packs. Bright colors and clear digits make circuits easier to trace and maintain. Key benefits Fast visual identification of wires by color and digit, reducing time spent tracing circuits during installation and maintenance. Snapon clip design installs quickly on individual wires or in strips, including wires with connectors or terminal blocks. Secure fit keeps markers in place for longterm organization without slipping off during normal use.
