Zip endings and stoppers.
A zip end is a special cap that is placed on the open edge of the zip and attached with a screw. It will be useful not for metal roll zips but also for spiral zips as well.
The lock or stopper for a metal zip is designed to control the movement of the slider. The upper stopper serves to restrict each half of the zip, while the lower stopper connects the two parts. There are different variations of locks: more expensive ones, such as X-shaped and U-shaped ones, as well as more affordable simple stoppers.
