Designed for where durability meets demanding conditions, the YKK Vislon #10 separating zipper auto lock double pull plastic slider in 108-inch white redefines outdoor fastening. Its injection-molded plastic teeth, molded from acetal or polyacetal resin, deliver a high level of chemical resistance and reliable performance--far surpassing ordinary metal zippers that corrode under moisture and sunlight. Each tooth and slider is color-integrated directly into the molding process, preventing chips or peels, while the corrosion-resistant, lightweight construction ensures easy handling without sacrificing strength. Double pull auto-lock sliders let you open or close this separating zipper smoothly from either end, ideal for large marine awnings, weatherproof jackets, heavy-duty tents, and straight industrial applications. Unlike conventional designs, this one-piece teeth profile resists salt air, abrasive outdoor environments, and UV exposure, and remains unaffected by changing temperatures and humidity. The dense polyester tape offers a secure, low-profile finish suitable for nearly any rugged outdoor project--trim, wrap, drop, or curtain, this versatile, weatherproof zipper adapts seamlessly.
