So, can you name the 12 parts of a zipper? Here they are:
1 - top tape extension
2 - top stop
3 - slider
4 - pull tab
5 - tape
6 - chain width
7 - bottom stop
8 - bottom tape extension
9 - single tape width
10 - insertion pin
11 - retainer box
12 - reinforcement film
So if you think about it, using a zipper is quite an undertaking. You've got to make sure the slider is lined up with the retainer box all the way down to the bottom stop, then make sure the insertion pin is in place before using the pull tab to move the slider along the chain to the top stop.
And...did you know that 90% of the world's zippers are produced in Japan? Fascinating. How did we survive without the WWW and sites like Wikipedia??? Thanks to Wikipedia for the detailed photo.
