The Henkel Duck all-purpose "Duck" tape is Henkel"s original Duck-brand duct tape. This silver-colored tape is perfect for countless repairs around the home, school, or office, both indoors and outdoors. Its Dura Bond construction uses a thick, heavy-duty adhesive applied to a waterproof cloth backing for extra durability and to resist delamination in direct sunlight. The tape adhesive features a high initial tack, and it readily conforms to uneven surfaces for maximum adhesion. The cloth outer layer is also reinforced with cloth mesh for extra tensile strength, yet it tears easily without curling, making one-handed application possible. The tape comes in a 1.88-inch-by-45-yard roll.
