3M Company 3920-BL Multi-purpose Duct Tape 1.88in X 20yd Blue

Product Description

The 3M COMPANY 3920-BL is a multi-purpose duct tape supplied in a blue colorway, measuring 1.88 inches wide by 20 yards long. It features a durable, waterproof backing that tears easily by hand without the need for a cutter. The adhesive applies smoothly and maintains a secure bond on curved and irregular surfaces. Intended for a wide range of light-duty tasks, the 3920-BL is a practical consumable stocked by contractors, facilities technicians, and maintenance crews who need a reliable general-purpose tape on the job site or in the shop.

The blue color makes this tape a practical choice for discrete repairs, temporary holds, organization, color coding, and craft or decorating applications. Its hand-tearable construction speeds up workflow when precise cutting tools are not available. Sold in cases of 12 rolls, it suits bulk procurement for facilities management, trade shops, and supply rooms that go through tape volume regularly.

Installation Notes

Surface should be clean, dry, and free of dust or oils before application to ensure proper adhesion. For best results on curved surfaces, apply with moderate hand pressure and smooth from the center outward. This tape is intended for temporary or light-duty use and is not a substitute for code-rated mechanical fasteners or listed sealing materials in HVAC duct assemblies. Remove tape from painted or finished surfaces with care to avoid substrate damage.
