The Henkel Duck professional "Duck" tape is professional-grade duct tape, featuring thicker cloth with more fibers per square inch for extra-strength performance, and is ideal for both professional use and do-it-yourself jobs. Its Dura Bond construction uses a thicker, 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.
