A 4-inch black cloth tape (commonly referred to as black gaffer or duct tape) is a heavy-duty, polyethylene-coated woven cloth adhesive tape designed for high-strength bundling, surface protection, sealing, and temporary cabling containment. Formulated with a aggressive pressure-sensitive rubber adhesive, it secures firmly to smooth, rough, or irregular surfaces while tearing cleanly by hand along both axes. Its extra-wide 4-inch (100mm) profile provides high coverage and superior tensile strength, while the non-reflective matte black finish makes it ideal for discreet maintenance, staging, and industrial site applications where light reflection must be minimized.
