3M 7000031517 Wire Marker Tape Refill Roll Letter B

Product Description

The 3M 7000031517 is a printed wire marker tape refill roll designed for clear, durable wire and cable identification in electrical installations. Each roll is pre-printed with the letter B, allowing technicians to label conductors quickly and consistently without hand-marking. These refill rolls are sold in boxes of 10 and are intended for use with compatible 3M wire marker dispensers. Electricians and low-voltage technicians rely on standardized wire markers like these to maintain legible, code-consistent labeling across panel boards, junction boxes, and conduit runs.

These marker rolls are suited for commercial and residential electrical work where conductor identification is required by inspection or code. The pre-printed format speeds up termination workflows on large wiring jobs, helping technicians mark multiple conductors of the same designation without preparing individual labels. Typical applications include panel wiring, motor control centers, and multi-conductor cable terminations where repeated letter designations are needed across a circuit.

Key Features

• Pre-printed with letter B for consistent, legible wire identification
• Tape roll format compatible with 3M wire marker dispenser systems
• 10 rolls per box for high-volume labeling jobs
• Supports code-compliant conductor identification at termination points
• Lightweight refill format minimizes bulk in tool bags and service vans

Compatibility

Designed as a refill roll for use with compatible 3M SDR-series wire marker tape dispensers.

Installation Notes

Wire marker tape is applied by licensed electricians and low-voltage technicians during conductor termination and labeling. De-energize all circuits before working at termination points, per NFPA 70 lockout/tagout requirements. Apply markers to clean, dry conductor insulation to ensure adhesion and legibility. Do not apply tape over damaged or contaminated insulation.
