Constructed of polyethylene film laminated to cloth with a rubber adhesive, this economical tape resists curling and tears off the roll cleanly for use in MRO/construction. 3M™ Contractor Grade Pro Strength Duct Tape 3979 is economically priced to provide a medium-strength, temporary solution. It is removable with little or no adhesive residue up to three months after application.
Originally developed for heating, ventilating and air conditioning (HVAC) applications, duct tape is used today in a variety of maintenance, repair and construction settings. Our 3M™ Contractor Grade Pro Strength Duct Tape 3979 was tested according to UL723, ASTM E84. Due to its unique design and price, it is a strong choice for general indoor, everyday duties where strength and moisture resistance are necessary. The contractor-grade tape can also be used at temperatures as high as 200°F for up to 30 minutes.
3M™ Contractor Grade Pro Strength Duct Tape 3979 comes with a classic, silver-colored backing. Our sturdy cloth-reinforced tape can be torn from the roll and sticks instantly, providing a wide range of convenient solutions.
