3M 7100085113 Red Duct Tape 3920-RD 1.88in X 20yd 12-pack

Product Description

The 3M 7100085113 is a red duct tape sold under the 3920-RD designation, supplied in a case of 12 rolls. Each roll measures 1.88 inches wide by 20 yards long, providing a practical length for duct sealing, bundling, color-coding, and general trade applications. The red color makes it suitable for identification and marking tasks where a high-visibility tape is required. It carries a unit-of-measure designation of Roll and is packaged to meet a minimum order quantity of 12 rolls per case, making it appropriate for stocking in a service van or supply room.

This tape is used across HVAC, plumbing, electrical, and general mechanical service work where a cloth-backed pressure-sensitive tape is needed. The red color is commonly applied for color-coded identification of conduit runs, pipe groupings, bundled wiring, or duct sections. It is also used for temporary repairs, masking, and general holding tasks in both residential and light commercial service environments.

Installation Notes

This tape is applied by hand and requires no specialized tools. Ensure the application surface is clean, dry, and free of dust or oils before applying for maximum adhesion.
