3M 7000124264 Performance Plus Duct Tape 8979 Slate Blue

Product Description

The 3M 7000124264 is a heavy-duty duct tape engineered for both permanent and temporary fastening applications in indoor and outdoor environments. Sold as the Performance Plus Duct Tape 8979 in slate blue, this roll measures 144mm wide by 54.8 meters long with a 12.1 mil total thickness. The construction allows clean removal from most opaque surfaces with little or no adhesive residue for up to 6 months after application. The backing resists UV degradation for up to one year of outdoor exposure, making it a reliable option for seasonal or extended exterior use. HVAC technicians, sheet metal workers, and general contractors are the primary installers.

This tape is suited for a wide range of trade and industrial applications where a conformable, removable, or semi-permanent bond is needed. Common uses include sealing ductwork, bundling insulation, temporary masking during construction, and general repairs on job sites. Its slate blue color distinguishes it from standard silver duct tape, which can be useful for color-coded workflows or applications where the tape must be visually identifiable after installation. It performs in both indoor conditioned spaces and outdoor exposed environments.

Installation Notes

Surface preparation is critical — clean and dry the substrate before applying to ensure proper adhesion. Apply firm, even pressure across the full tape width using a roller or hand pressure for maximum contact. When used on ductwork, follow applicable local mechanical codes and manufacturer guidelines regarding tape ratings for air-sealing applications. Power down or isolate any system before applying tape near energized components.
