3M Company 3960-BK Multi-purpose Duct Tape 1.88in X 60yd Black

Product Description

The 3M COMPANY 3960-BK is a black multi-purpose duct tape designed for general-purpose sealing, bundling, patching, and organizing tasks across residential, commercial, and light industrial settings. The tape measures 1.88 inches wide by 60 yards long and features a durable, waterproof backing that tears cleanly by hand without tools. It applies smoothly to flat and curved surfaces, maintaining a reliable hold without lifting or flagging. HVAC techs, plumbers, electricians, and facility maintenance crews keep this tape on hand for quick discrete repairs, color-coded organization, and craft or decorating applications where a clean black finish is preferred.

The 3960-BK is suited for a wide range of applications including temporary duct patching, cable and wire bundling, surface protection, and job-site organization. Its black color makes it a practical choice for discrete repairs where a low-visibility finish matters. The waterproof backing holds up in damp or humid environments, making it useful in mechanical rooms, crawlspaces, and outdoor temporary repairs. Sold individually per roll, with a package quantity of 9 rolls per case for stocking purposes.

Installation Notes

Apply to clean, dry surfaces for best adhesion.
