Zipper hardware refers to the components that make up a zipper, which is a common fastening device used in clothing, bags, and other items. The main parts include the slider, which moves up and down to open or close the zipper, and the teeth, which interlock to secure the closure. Zippers can be made from various materials, such as metal, plastic, or nylon, and come in different sizes and styles. In addition to the slider and teeth, zipper hardware also includes the stopper at each end, which prevents the slider from coming off, and the tape, which holds the teeth in place. Zippers can be found in many applications, from jackets and jeans to backpacks and suitcases, making them an essential part of everyday items.
