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. Due to its unique design, our Multi-Purpose Duct Tape 3900 is an excellent choice for general indoor application in MRO/construction. The tape can be used at temperatures as high as 200°F for up to 30 minutes.
Multi-Purpose Duct Tape 3900 comes in an array of colors for process tagging, marking, highlighting hazards, color coding, identification and visual enhancement. Our sturdy cloth-reinforced tape can be torn from the roll and sticks instantly, providing a wide range of convenient solutions.
