Classification of zippers by structure

①Closed zipper. The rear yard is fixed and can only be pulled away from the front yard. When the zipper is fully opened, the two chain straps cannot be separated by the rear code. Suitable for ordinary bags.
②Open zipper. There is no rear code at the lower end of the tooth chain and a locking piece is provided. When the locking member is locked, it is equivalent to a closed zipper. Pull the slider against the locking member to separate the locking member, and the chain belt can be separated. Suitable for clothing or items that often need to be pulled apart.
③ Double zipper. There are two sliders that can be opened or closed from either end. Full opening is achieved by pulling both sliders against the tight locks to separate them. Suitable for large bags, bedding, tents, etc.
