3M 7000031536 Wire Marker Tape Refill Roll Letter U

Product Description

The 3M 7000031536 is a printed wire marker tape refill roll designed for fast, legible wire identification in electrical and low-voltage wiring applications. Each roll is pre-printed with the letter U, eliminating the need for hand-labeling individual conductors. These refill rolls are sold in boxes of 10 and are sized for use with compatible 3M wire marker dispensers. Licensed electricians and low-voltage installers use these markers to meet labeling requirements and keep panel and conduit work organized and inspection-ready.

These wire marker tape refill rolls are suited for commercial and residential electrical work where consistent conductor identification is required. Common applications include panel wiring, control wiring, and instrumentation runs where conductors must be identified at termination points. The pre-printed letter U covers a common designation used in single-phase and multi-phase circuit labeling. Each roll is a drop-in refill for existing 3M marker tape systems already on the job site.

Installation Notes

Wire marker tape is applied by qualified electricians and low-voltage technicians during conductor termination or panel dressing. De-energize all circuits and follow NFPA 70 (NEC) lockout/tagout procedures before working inside panels or enclosures. Apply markers to clean, dry conductor insulation to ensure adhesion and long-term legibility. Do not apply to conductors under tension or in areas where the tape may contact moving parts.
