Built for challenges the outdoors brings, the YKK Vislon #10 Lock Slide 30-inch zipper in grey pairs heavy-duty strength with surprising lightness thanks to its injected molded plastic teeth--offering marine-grade durability without the weight of metal alternatives. This corrosion-resistant and UV-resistant plastic zipper features a reliable locking slider, a double pull tab for effortless access from either side, and is backed by tough polyester tape for lasting performance. Equally at home on marine gear, convertible tops, industrial covers, or outdoor awnings, it's also designed to work with continuous zipper chains, meaning installation is seamless on larger projects. Choose it for applications where exposure to the elements, chemicals, or heavy use would quickly wear down ordinary fasteners. The 30-inch length suits a range of custom needs, and the sleek grey finish fits discreetly into a variety of outdoor settings, ensuring both function and style stay intact wherever you install it.
