3M Heavy Duty 3939 Duct Tape, 2" x 60 Yards

Constructed of polyethylene film laminated to cloth with a rubber adhesive, this durable tape resists curling and tears off the roll cleanly for easy application in MRO and construction. 3M™ Heavy Duty Duct Tape 3939 has a construction that allows for permanent and temporary applications. It is removable with little or no residue up to one month after application to opaque, non-glass surfaces. It is ideal for heavy-duty use in MRO and construction applications. Removes cleanly for up to one month from many opaque, non-glass surfaces when applied indoors. Sticks immediately and stays for up to one year without deterioration when applied indoors. Strong water-resistant backing resists wear and light abrasion and provides a tight, moisture-resistant seal in many containment situations. Conforms to irregular surfaces without lifting.
