A heavy-duty YKK Vislon #10 separating zipper delivers reliable, all-weather performance for outdoor marine, tent, and upholstery uses--instantly improving both function and style. Molded black plastic teeth crafted from injection-molded polyacetal resin resist corrosion, moisture, and UV rays, setting it apart from traditional metal zippers with a lighter weight and proven durability. The 78-inch length, adjustable for larger projects, features a double-pull AutoLok slider for easy access from either end, while the nylon slider and separation feature make this heavy-duty jacket or marine zipper as practical as it is sturdy. Outdoor enthusiasts and DIY decorators will appreciate the subtle difference in handling--smoother, quieter, and reliably weather-resistant--that's made to stay strong under heavy use.
