3M 7000031517 Preprinted Tape Refill 8 Ft Character B

Product Description

The 3M 7000031517 is a preprinted polyester film tape refill designed for wire and cable marking applications. The refill carries the character B on a white background and uses a self-adhesive attachment style, allowing labels to wrap and adhere directly to wires, cables, or other cylindrical surfaces without additional tools. Each roll measures 8 feet in length and 0.215 inches wide, yielding multiple labels from a single refill. The polyester film substrate resists moisture and abrasion, making it suitable for use in electrical panels, conduit runs, and equipment rooms. Licensed electricians and low-voltage technicians are the primary installers of this type of marking system.

This tape refill is used in commercial and residential electrical installations where consistent, legible wire identification is required. It is compatible with label dispenser and marker systems that accept 0.215-inch-wide polyester film refills. The character B designation makes this refill appropriate for any application where conductors, terminals, or circuits must be labeled with that specific character. Panel builders, systems integrators, and field electricians commonly stock individual character refills for on-demand labeling during installation or maintenance.

Installation Notes

Installation is performed by licensed electricians or low-voltage technicians following applicable NEC guidelines for wire identification. Power down or de-energize the circuit before applying labels to conductors. Ensure the surface is clean and dry prior to application so the self-adhesive backing bonds fully. Labels applied to polyester film should be pressed firmly to prevent lifting in high-humidity or high-vibration environments.
