3M 7000031521 Wire Marker Tape Refill Roll Letter F

Product Description

The 3M 7000031521 is a printed wire marker tape refill roll designed for use with compatible 3M wire marker dispensers. Each roll is pre-printed with the letter F, providing clear, consistent wire and cable identification in electrical installations. The refill format allows technicians to reload existing dispenser tools without replacing the full unit, reducing waste and keeping labeling workflows uninterrupted. These rolls are sold in a box of 10, making them practical for ongoing jobsite or panel shop use by licensed electricians and electrical contractors.

Wire marker tape refill rolls like the 7000031521 are used in residential, commercial, and light industrial electrical work where circuit and conductor identification is required. Common applications include panel wiring, conduit runs, control wiring, and low-voltage cabling where conductors must be labeled for inspection compliance and long-term serviceability. The letter F designation suits specific conductor or circuit labeling schemes used by electricians following NEC identification requirements.
