3M SDR-B Wire Marker Tape

Product Description

The 3M SDR-B is a wire marker tape designed for labeling and identifying wires, cables, and conductors in electrical installations. Wire marker tape provides a durable, readable label that stays in place through the demands of trade work, including exposure to heat, moisture, and repeated handling. Electricians and low-voltage technicians use this type of marker tape to meet identification requirements on residential, commercial, and industrial wiring projects. It is a standard identification consumable kept on hand by installers who need reliable, legible wire labeling at the point of termination or in panel work.

Wire marker tape is commonly applied during rough-in and finish electrical work wherever circuit identification is required. Typical applications include panel boards, junction boxes, conduit runs, and low-voltage wiring systems. The SDR-B format is suited for use by licensed electricians and low-voltage technicians working on projects where NEC-compliant conductor identification is part of the installation requirement.

Key Features

• Durable tape construction stands up to handling in panel and junction box environments
• Provides clear, lasting wire and cable identification
• Suitable for residential, commercial, and industrial electrical applications
• Compact form factor supports use in tight wiring spaces

Compatibility

Designed as an OEM-style wire identification solution for general electrical wiring and cable labeling applications across residential and commercial installations.

Installation Notes

Wire marker tape is applied by electricians and low-voltage technicians as part of standard conductor identification workflow. Power down or de-energize circuits before working in panels or junction boxes where markers are being applied. No special tools are required for application. Follow NEC guidelines for conductor identification requirements on your specific project type.
