Every tech has done the electrical-tape dance: wrap a band of colored tape around a wire for identification, watch it unravel, gum up, or bake off in a hot attic six months later.
The U-Phase permanent wire marker replaces that ritual in seconds — a large-tip paint marker made specifically for wire and cable, laying down a fast-drying permanent band of color that stays put for the life of the installation.

The applications are everywhere you pull wire: identifying runs in a pre-wire before the drywall goes up, phasing conductors in an electrical panel, tagging which coax goes where in a structured-wiring can, marking fiber, CAT5e/6/7, HVAC control wiring, AV runs, automation cable — anywhere you'd otherwise reach for tape or struggle to write on a round jacket.
Draw a band, a dot, or a stripe pattern; the paint bonds to wire jackets and stays legible.

This is the black marker, ideal for marking lighter-colored jackets.
Stock a few colors and you have an instant, durable wire identification system for the whole crew.
