without guessing.

3M wire marking products help electricians and industrial teams label conductors quickly, clearly, and permanently.

Whether you’re marking inside a panel, routing low-voltage wiring, or preparing for inspection, 3M wire markers hold tight and stay visible.

Summit Electric Supply stocks a full range of 3M labeling materials for field use, panel work, and industrial printers. With options for hand-applied tags, adhesive-backed tapes, and thermal printable formats, we help you find the right fit for your conductor size, voltage class, and labeling system. Our team makes sure your markers go on clean and stay legible from rough-in to closeout.
