Economical choice, good for multi-purpose applications

A Tape with Versatility
Originally developed for heating, ventilating and air conditioning (HVAC) applications, duct tape is used today in a variety of maintenance, repair and construction settings. 3M™ Contractor Grade Multi-Use Duct Tape 2979 was tested according to UL723, ASTM E84. Due to its unique design, it is a good choice for light indoor, everyday jobs where moisture resistance is a factor. The tape can also be used at temperatures as high as 200°F for up to 30 minutes.

3M™ Contractor Grade Multi-Use Duct Tape 2979 comes with a classic, silver-colored backing. 3M sturdy cloth-reinforced tape can be torn from the roll and sticks instantly, providing a wide range of convenient solutions.
