Economical contractor-grade duct tape with aggressive adhesive and cloth-reinforced backing for everyday maintenance, repair, and light construction applications. Hand-tearable, conformable, and ideal for indoor use.
3M™ Contractor Grade Multi-Use Duct Tape 2979 is an economical, lighter-duty duct tape designed for everyday indoor maintenance, repair, and construction applications. Constructed of polyethylene film laminated to cloth with a synthetic rubber adhesive, this versatile tape resists curling and tears off the roll cleanly for convenient use in MRO and construction settings. Originally developed for HVAC applications, this silver-colored duct tape has evolved to serve a wide range of maintenance, repair, and construction needs where moisture resistance is essential.
The tape features an aggressive synthetic rubber adhesive that grips reliably to a wide variety of surfaces, while its stretchable, cloth-reinforced backing conforms to irregular surfaces and tight spaces without lifting. The hand-tearable backing and fast-bonding adhesive make it easy to work faster on temporary repair jobs. With reinforced cloth construction, this tape provides the high tensile strength needed for light bundling applications. It can be used at temperatures as high as 200°F for up to 30 minutes and is removable with little or no adhesive residue up to three months after application.
Each case contains 24 individually wrapped rolls of 1.88 inch by 60 yard tape, making it convenient for job sites and storage. This economically priced tape is an excellent choice for multi-purpose applications including patching, light bundling, tabbing, taping/splicing insulation, capping pipe, securing conduit ends, marking, labeling, and temporary repair work. Available in classic silver color, 3M's Contractor Grade duct tape is known for its hand tearability, high tensile strength, and conformability.
