![]() Now that we've covered zipper chain, let's turn to sliders - the piece that zips and unzips the chain. How do locking and non-locking zipper sliders work? We'll tell you. If you don’t sew one or both ends of your continuous zipper shut, you can add stops to the chain to keep the slider from falling off the end(s). Continuous zippers are usually sewn into a project - like a bag, tent or cushion - at one or both ends. ![]() These zippers do not come with sliders, so you will have to purchase one separately and add it to the zipper chain. You can order continuous chain in preset lengths and cut it to the length you need for your project. These zippers do not have a beginning or end point (no preinstalled starter box or zipper stops). Just make sure you add stops to the cut end or sew it into your application so you don’t lose your slider!Ī continuous zipper is a little different. Non-separating finished zippers are good for bags, jacket pockets and more.Īll styles of finished zippers come in preset lengths, but you can cut them shorter if needed. Both of these zipper types have permanent stops at both ends, but bridge top zippers have one slider while bag style zippers have two. Sailrite carries two varieties of non-separating finished zippers: bridge top and bag style. They have preinstalled sliders and stops, but no starter box or pin. On the other hand, the two halves of non-separating finished zippers don’t come completely apart. You can even get water-repellent separating zippers! These zippers are used for applications where the sides of the zipper should separate completely, such as on a coat, a genoa sleeve or the side panels of a cockpit enclosure. They feature a starter box and pin at one end of the zipper tape and stops at the other end. Separating zippers are sometimes also called "jacket zippers" because they are most commonly used on coats and jackets. Within the category of finished zippers, there are separating and non-separating zippers. You don’t have to add any parts to a zipper like this - it’s already finished. ![]() Finished zippers are called this because they come with stops, sliders, and sometimes a starter box and pin preinstalled. "Continuous" and "finished" are terms that refer to the length and style of a zipper as a whole. ![]() Right: a fully separating finished zipper. You'll find a selection of metal zippers on our website. They are ideal for bags and purses, backpacks, interior cushions and upholstery, and more. Because they can corrode, we recommend not using metal zippers for outdoor projects. Metal zippers have polished metal teeth that secure together on the zipper chain. We stock coil zippers in sizes #4.5, #5 and #10. Just note that polyester thread breaks down in the sun, so coil zippers should be kept covered to protect them from UV exposure in outdoor projects. Coil zipper teeth are stronger and more flexible than molded tooth zippers, making them a great choice for indoor and outdoor projects with curves. The teeth are sewn onto the side tape with polyester thread. We stock molded tooth zippers in sizes #5, #10, #12 and #15.Ĭoil zippers feature nylon teeth that, as the name implies, look coiled. ![]() Molded tooth zippers are the most common option for marine projects because they’re UV and corrosion resistant. (YKK ® molded tooth zippers are called VISLON ® Lenzip ® doesn't use a special term.) This construction makes them strong and practically weatherproof. The molded tooth zippers we carry are made from DuPont Delrin ® Acetal Resins molded onto zipper tape. A close-up view of the three zipper chain types. ![]()
