These heavy duty zippers and industrial zippers for sewing are designed for coats, work jackets, tents, canvas, sleeping bags, duffel bags, military bags, and other applications that require zippers with extra strength. Heavy duty zippers, available individually and also in bulk at a discount, are particularly handy for sewing replacement zippers into construction workers’ jackets, coveralls, chaps, leather jackets, motorcycle jackets, and other durable gear. Did the zipper break on your most rugged jacket? Consider replacing it with a new heavy duty zipper and you can extend the jacket’s life with a simple repair!
Heavy duty zippers are available with metal zipper teeth (brass, antique brass, aluminum, nickel) and heavy duty molded plastic zipper teeth. The heavy duty zippers found here are #10 gauge zippers, which means the teeth measure approximately 10 millimeters (about 1/2 inch) across when zipped. They are very wide zippers and much sturdier than the medium weight #5 zippers (5 mm across / about ¼ inch) which are commonly found in retail stores as “heavy duty zippers.”
