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.
