3M SDR-L2 Wire Marker Tape

Product Description

The 3M SDR-L2 is a wire marker tape designed for identifying and labeling electrical conductors, cables, and wiring harnesses in the field. Wire marker tapes provide a fast, legible, and durable identification method that resists smearing and slipping on wire insulation. This product is suited for electricians and low-voltage technicians who need reliable conductor identification during installation, inspection, or service work on residential, commercial, or industrial electrical systems.

Wire marker tape is commonly used in panel wiring, conduit runs, control panels, and low-voltage wiring applications where clear conductor identification is required by code or by inspection protocol. It applies quickly by hand, making it practical for in-field use without specialized tools.

Key Features

• Tape-format wire marker for fast field application without tools
• Designed for labeling individual conductors, cables, and wiring harnesses
• Resistant to smearing for lasting legibility after installation
• Suitable for residential, commercial, and industrial electrical work
• Compact format supports use in tight panel and conduit environments

Compatibility

Designed as an OEM-style wire identification solution compatible with standard electrical conductor and cable insulation surfaces used in typical residential and commercial wiring installations.

Installation Notes

Wire marker tape is installed by licensed electricians and low-voltage technicians. De-energize all circuits and follow OSHA lockout/tagout procedures before labeling conductors in live panels or enclosures. Apply markers prior to final termination for easiest access, and verify legibility before closing the enclosure. NEC Article 310 and local inspection requirements may specify conductor identification standards on certain installations.
