    A genuine YKK Vislon No.8 open-end coat zip with chunky moulded plastic teeth — available in 14 colours and five long lengths, made in the UK. Brand: YKK Range: Vislon Material: Moulded plastic teeth, 35mm woven tape Gauge: No.8 (8mm tooth width) Type: Open end (separating) Lengths: 24 inch (61cm) · 26 inch (66cm) · 28 inch (71cm) · 30 inch (76cm) · 32 inch (81cm) Colours: Black · Navy · Royal Blue · Brown · Ivory · Light Ecru · Fawn · Khaki · Forest Green · Dark Grey · Burgundy · Red · Dark Wine · White Pack size: Sold individually (1 zip per order) HS Code: 9607110000 Country of Origin: United Kingdom The YKK Vislon No.8 is the go-to heavy-duty open-end zip for full-length coats, long parkas, maxi outerwear, and performance garments where a shorter jacket zip simply won't reach. At 8mm, the No.8 gauge teeth are substantially larger than the No.5 found in most everyday garments, delivering a stronger, more positive fastening that stands up to repeated daily use. The open-end construction means the zip separates fully at the base — the standard requirement for any garment that opens completely. The wide 35mm tape provides a generous seam allowance, ideal for stitching securely into heavier coat and parka fabrics. How to Order: Select your preferred Colour from the dropdown (14 options available). Select your required Length — 24, 26, 28, 30, or 32 inch. Add to basket and proceed to checkout. Colours may appear slightly different depending on your monitor settings and lighting conditions. Note: colour 578 (Dark Grey) appears closer to a mid-grey tone in real-world lighting. If colour matching is critical, we recommend ordering a sample first.
