A Tape with Versatility
Originally developed for heating, ventilation and air conditioning (HVAC) applications, duct tape is used today in a variety of maintenance, repair and construction settings. 3M™ Heavy Duty Duct Tape 3939 is an excellent choice for general indoor application in MRO and construction. The tape was tested for flame spread using test method UL723, ASTM E84 and can be used at temperatures as high as 200°F for up to 30 minutes. The sturdy cloth-reinforced tape can be torn from the roll by hand and sticks instantly, providing a wide range of convenient solutions. This tape has a classic silver-colored backing.
