线圈拉链

I have a regular nylon coil zipper, but the back of the slider just has an "A" on it. The puller has YKK stamped, but I can't tell what teeth size it is. help!

Hi @edbohl35755 zips are ususally measured in millimetres. Just measure the across the teeth and you'll likely get something like 3mm or 5mm, these are the standard sizes for coil zippers (at least in Germany, let's hope in the US sizes aren't measured in sixteenths of an inch...). Once you know the size of your zip, you should be able to get a replacement zipper. Hope this helps :)
