YKK | 雙向 | 開口拉鍊 | 金屬 | 黑色 | #10 | 30 3/4 英吋 - 78 公分

This heavy-duty #10 zipper handled my boat cover project perfectly. The two-way opening makes it so much easier to get in and out compared to a standard separating zipper.

I was worried about finding a zipper tough enough for my boat cover, but this two-way separating one has held up perfectly in the wind and salt spray. The metal teeth are substantial and the slider action is smooth, even with the heavy fabric.

All the metal teeth align perfectly and the #10 gauge feels heavy-duty enough for my truck’s canvas cover. The two-way slider actually works smoothly in both directions, which is rare for an open-end zipper this size.
