3M 7000031766 Wire Marker Label Refill Roll Write-on

Product Description

The 3M 7000031766 is a write-on wire marker label refill roll designed for use with the 3M SWD dispenser. Each roll contains 50 labels sized at 0.75 x 1.375 inches, with a dedicated write-on area measuring 0.75 x 0.312 inches. These markers wrap around wire and cable to provide clear, field-written identification at termination points, junction boxes, panels, and pull points. Electricians and low-voltage technicians rely on write-on markers when circuit labeling must be completed on the job without pre-printed stock. The label stock is sized to fit wire with an outer diameter of 0.09 to 0.31 inches.

This refill roll is suited for residential and commercial electrical work where wire identification is required at panels, switchgear, conduit runs, and device terminations. It is commonly used by licensed electricians, low-voltage installers, and data and communications technicians who need a fast, readable marker for conductors and control wiring. The compact refill format is intended to reload existing SWD dispensers already in use on the job site, keeping labeling workflows uninterrupted.
