Elevate your outdoor gear, tents, or marine coverings with the YKK Vislon #10 Black Separating Zipper. This 24-inch heavyweight zipper features large, molded plastic teeth for reliable, weather-resistant performance--even in salt, sand, or chemical exposure. Unlike metal zippers, its acetal plastic construction is inherently corrosion-resistant, extremely durable, and surprisingly lightweight, making it ideal for marine, patio, or industrial use. The smooth, self-lubricating glide resists jamming, while polyester tape and both double or single pull tab options provide flexibility and ease for replacement zipper applications. Whether for awnings, convertible tops, cushions, or jackets, this open-end, one-way separating zipper brings together seamless operation and tough reliability where it matters most.
