3M™ Heavy Duty Duct Tape 3939(pc)

3M™ Heavy Duty Duct Tape 3939 is a silver-colored duct tape developed for demanding maintenance, repair, and construction (MRO) work. Its polyethylene-coated cloth backing combines flexibility with durability, while the rubber adhesive provides quick bonding to many surfaces.

The tape is designed to handle temporary and permanent tasks such as securing, patching, bundling, reinforcing, sealing, and protecting materials. It can conform to irregular surfaces and is designed to resist curling, wear, moisture, and light abrasion. It can also be removed indoors for up to three months with little or no adhesive residue under the conditions described by 3M.
