YKK Vislon #10 Locking 2-Tab Slider in black features a low-profile, double pull design for operation from either side, equipped with a locking mechanism that prevents unwanted slider movement. Made from durable, corrosion-resistant acetal plastic, this lightweight slider is built specifically for #10 molded tooth Vislon zipper chains. It offers reliable performance in marine, outdoor, tent, awning, and upholstery applications, resisting chemicals, UV rays, and extreme temperatures. Ideal for reversible zipper projects, its color is integrated into the molding to prevent chipping or fading, providing a long-lasting replacement option for enhancing outdoor living and patio gear.
