These nylon zippers are professional, heavy-duty zippers designed for upholstery. Their strong construction helps ensure it does not break open. Zipper slides are not included with the zipper chain and can be ordered here.
Measure the necessary length of the slipcover and cut the zipper to length. To avoid running short, cut the zipper length several inches longer than necessary. The additional zipper length can be cut off after installation.
Once the zipper is cut to the appropriate length, split the zipper end open and place the zipperhead on one side and place the other side into the zipperhead while pulling the zipperhead down the length. This will join the two halves together, creating a complete zipper in length with the zipperhead attached.
