YKK | قفل شبه تلقائي | سحاب مغلق الطرف | معدن | #4 | 4 3/4'' - 12 سم

Bought this for a trouser alteration and the closed-end metal teeth slide smoothly without catching. The 4 3/4 inch length was exactly right for the project.

The auto-lock slider is a game-changer for my hiking gear bag, clicks into place firmly so nothing spills open. I used it to replace a worn-out zipper on a field jacket, and the metal teeth glide smoothly even after repeated use. It’s the perfect length for my repair project.

Had to swap out a broken zipper on a vintage jacket and this closed-end metal YKK was a perfect fit—the auto-lock slider keeps the pull tab firmly in place when it's upright, which is exactly what I needed. Took maybe 15 minutes to sew in and it glides smoothly so far.
