A zipper, known by many as a locker, is mostly used for bringing together the edge of an opening. That opening can be made of fabric or flexible materials such as a bag or a garment. Zippers are generally used in clothing, luggage, sporting and camping gears.
Zippers are of different types such as coil zippers, invisible zippers, metal zippers, reverse coil zippers, open-end zippers, two way open-end zippers and plastic molded zippers. Here are some important definitions you should know to assist in your zipper needs.
Chain: The chain of the zipper is a piece that is continuous and is formed when both sides of the zipper are brought together.
Continuous Chain: Refers to a zipper chain that can be spooled continuously without sliders.
Chain Size: It refers to the gauge of the chain – some gauge sizes commonly used are #3, #5, #7 and #10. The bigger the gauge size, the wider the teeth will be.
Slider: This is a device that moves down the chain to open the zipper, and up to close the zipper. There are different types of sliders used, depending on the needs of the user.
