#7GS-SZ8-FB-PET-DC-7#
Grooved Eight-Thread Explosion-Proof Zipper
A shielded track keeps every seam aligned through harsh handling.
The #7 grooved eight-thread model is designed for medium-large reusable bags, outdoor packs, and canvas storage. An integrated groove in the tape positions the eight stitching lines and separates them from direct slider friction. Four-needle eight-thread sewing and dual-layer, dual-track polyester coil teeth improve seam alignment, flatness, and load distribution through repeated handling and cleaning.
Key Features
- ✓Integrated groove protects stitching from wear
- ✓Eight-thread edge lock prevents tearing
