3M SDR-T2 Wire Marker Tape

Product Description

The 3M SDR-T2 is a wire marker tape designed for permanent, legible identification of wires, cables, and conductors in electrical and low-voltage installations. The tape format allows technicians to apply consistent, durable labels directly to wire runs without the need for specialized tools or printers. Wire marker tape is a standard consumable in panel wiring, circuit labeling, and service work where accurate identification is required for troubleshooting, inspection, and code compliance.

This product is suited for use in residential and commercial electrical applications, including panel boards, junction boxes, conduit runs, and low-voltage control wiring. Electricians and low-voltage technicians reach for wire marker tape during new construction rough-in, service upgrades, and retrofit work where identifying individual conductors and circuits is essential to safe and organized installations.

Key Features

• Tape format provides flexible application to wire and cable surfaces
• Designed for permanent conductor and circuit identification
• Suitable for use in electrical panels, junction boxes, and conduit installations
• Supports code-compliant labeling practices for inspections and service calls

Compatibility

Designed as an OEM-style wire identification solution compatible with standard wire and cable diameters commonly found in residential and commercial electrical installations.

Installation Notes

Wire marker tape is applied by electricians and low-voltage technicians as part of standard wiring practice. Always de-energize circuits before working in panels or junction boxes, following NEC lockout and tagout procedures. Ensure wire surfaces are clean and dry before applying tape to achieve proper adhesion. Do not apply over damaged insulation or use as a substitute for listed wire insulation.
