The Sleek, Modern Standard for Contemporary Tailoring!
The YKK No. 3 Silver Metal Zip (YARNC36) offers a crisp, professional finish for garments that require a modern aesthetic. Featuring a slim 3mm gauge with polished silver (aluminium) teeth, this zipper provides a high-contrast, clean look that is perfect for cool-toned fabrics like black, grey, navy, and white.
Designed for precision, the YARNC-36 is the preferred choice for tailors and designers who want the strength of a metal zipper without the heavy, industrial look of larger gauges. Its slender profile ensures it lies flat against the body, making it ideal for fitted trousers, elegant skirts, and premium lightweight accessories.
Key Features & Benefits
- Slim No. 3 Gauge: The 3mm silver teeth provide a refined, understated finish that won’t add bulk to your seams.
- Polished Silver Aesthetic: The bright aluminium finish offers a modern, high-end alternative to brass, perfect for contemporary fashion and “cool” colour palettes.
- Closed-Ended Construction: Specifically designed for fixed openings like trouser flies, skirt side-seams, and secure internal pockets.
- Semi Auto-Lock Slider: Equipped with a secure locking mechanism that prevents the zip from creeping down, ensuring total confidence during wear.
- Durable & Lightweight: Unlike heavier metal zips, the aluminium construction is lightweight yet resilient, preventing “fabric sag” on finer materials.
Ideal Applications
- Modern Tailoring: Men’s and women’s dress trousers, chinos, and smart shorts.
- Contemporary Dressmaking: Pencil skirts, sheath dresses, and light wool garments.
- High-End Crafting: Slim wallets, pouches, and luxury handbag interiors.
- Tech-Wear: Minimalist garments where a metallic, industrial look is desired in a small scale.
