U-Phase Wire Markers

U-Phase Wire Markers
Color phasing electrical panels, automotive wiring, and other wire circuit systems is easy with the U-Phase Wire Markers!

The unique U-shaped tip allows you to color around wires, cables, tubes, etc.- marking them with different colors for quick & easy identification. Marks with highly visible, quick-drying paint that permanently resists handling, heat, and UV light.

Quicker, less expensive, and more practical than using vinyl tape. Also, no more need to purchase and carry color specific wire!

*Now also available in a larger size capable of marking wires and pipes up to 3/4"!*
