Zip Terms explained

zip or zipper: a series of teeth that interlock and separate as we move the moving part up or down

slider or runner: the moving part of the zip (usually metal)

pull or puller: the top part of the runner that we catch and pull

zip coil: the series of teeth that form a plastic coil, applies to polyester zips only

zip teeth: metal or resin (plastic) teeth chain

stopper: small metal (or plastic) bits that terminate the slider movement

material (cloth): the material that the teeth or zip coil are attached to

open-ended zip: usually found on jackets, you have to join the two sides at the bottom of the zip before you can zip up

insert pin: the metal pin (or plastic) at the lower end of a jacket zip (found on open-ended zips)

insertion box: the metal small box (or plastic) at the lower end of a jacket zip, where the insert pin goes in to before zipping up (found on open-ended zips)

double-ended OR 2-way open-ended zip: a second slider here plays the role of the insertion box. The advantage is that you can un-zip from the lower end of the zip if you want.
