3M 7000132487 Pre-printed Wire Marker Book

Product Description

The 3M 7000132487 is a pre-printed wire marker book designed for labeling wire and cable in electrical installations. Each book contains 10 markers each of numeric designations 46 through 90, giving installers a ready supply of clearly numbered labels for circuit identification and panel organization. Wire marker books like this one are a standard tool in commercial and residential electrical work where accurate, legible wire identification is required for code compliance and long-term serviceability.

This marker book is suited for electricians and low-voltage installers working on panel wiring, conduit runs, control panels, and terminal block layouts. The pre-printed numeric format eliminates handwritten labels, reducing the risk of misread identifiers in high-density wiring environments. It is sold as an individual book.

Installation Notes

Wire marker books are applied by licensed electricians and low-voltage technicians during rough-in or trim-out phases of electrical work. De-energize circuits before labeling wiring in live panels in accordance with NFPA 70 (NEC) lockout/tagout requirements. Apply markers to clean, dry wire insulation to ensure proper adhesion and long-term legibility. Do not apply markers over damaged insulation or in environments exceeding the marker material rating.
