3M 4218-BA-40 Scotch Electrical Tape 0.75in X 66ft 40 Pack

Product Description

The 3M COMPANY 4218-BA-40 is a medium-grade Scotch electrical tape rated for continuous use up to 194 degrees F. Each roll measures 0.75 inches wide by 66 feet long, offering reliable insulation and protection for low-voltage wiring applications. The tape is sold in a bulk pack of 40 rolls, making it a practical stock item for electrical contractors, maintenance crews, and service technicians who go through tape at volume. Its temperature rating makes it suitable for standard residential and commercial wiring environments encountered in everyday service work.

This electrical tape is used for insulating splices, terminations, and wire bundles in residential and light commercial electrical installations. It is a common consumable on service trucks and in panel shops where quick, reliable insulation is needed. The 66-foot roll length extends time between changeouts, and the 40-roll pack format reduces restocking frequency on active job sites or in supply rooms.

Installation Notes

Electrical tape of this type is typically applied by licensed electricians or qualified maintenance technicians. De-energize and lock out circuits before taping any splice or termination, in accordance with NFPA 70E safe work practices. Apply the tape with moderate tension and overlap each pass by at least half the tape width to ensure a void-free insulation layer. Do not use as a substitute for listed wire connectors where connectors are required by NEC.
