3M SDR-L Wire Marker Tape

Product Description

The 3M SDR-L is a wire marker tape designed for clear, durable identification of wiring and cables in electrical and low-voltage installations. Wire marker tape is applied directly to conductor insulation or bundled cables to provide a legible, lasting label that survives the typical conditions found inside panels, junction boxes, and conduit runs. Electricians and low-voltage technicians rely on this type of marker to maintain code-compliant, readable circuit identification throughout a system's service life.

Wire marker tape such as the 3M SDR-L is suited for use in residential and commercial electrical work, including branch circuit labeling, control wiring identification, and panel termination marking. It is appropriate for any installation where permanent, hand-written or pre-printed identification of conductors is required by local code or standard practice.

Key Features

• Tape-style format allows direct application to wire or cable surfaces
• Designed for use in electrical panels, junction boxes, and conduit systems
• Supports code-compliant conductor identification practices
• Compatible with standard field-marking workflows used by electricians and low-voltage technicians

Compatibility

Designed as an OEM-style identification accessory for use in electrical and low-voltage wiring applications where conductor or cable labeling is required.

Installation Notes

Wire marker tape is installed by electricians and low-voltage technicians during rough-in, trim-out, or panel termination. De-energize all circuits before working inside panels or junction boxes in accordance with NFPA 70 (NEC) lockout/tagout requirements. Clean and dry the cable surface before applying the tape to ensure proper adhesion and legibility over time.
