Medium-Heavy #7 Nylon Coil Closed End Zipper with Auto-Lock Slider

MH #7 nylon coil zipper is a closed-end, medium-heavy gauge coil zipper built with polyester tape and nylon coil teeth.

The #7 gauge sits between the common #5 and the heavy #10, giving a wider, stronger coil that carries more load than lighter dress zippers. The auto-lock slider holds its position once set, so the closure stays put under tension.

It suits medium-to-heavy applications such as thick outerwear, jackets, luggage, travel bags, sleeping bags and tents.

Key Selling Points

• Medium-heavy load rating: The #7 nylon coil zipper carries more stress than #5 coil while staying lighter than a metal chain, making it a dependable fastener for thick coats, bags and outdoor gear.
• Secure auto-lock closure: The auto-lock slider grips the coil and holds its set position, keeping garments and luggage closed under movement and load.
• Smooth, flexible coil action: Nylon coil teeth on polyester tape run smoothly and bend easily around curved openings, so the zipper feels soft yet strong.
