For use with YKK zippers, this top stop prevents the slider from running off the zipper chain. Easily install the zipper stop end by placing it over a tooth on each side of the zipper and bending in place with pliers. It eliminates the need to cut the zipper and chain with a hot knife or sew it down to form a stop. Providing added flexibility, the stainless-steel zipper top stop can be moved if needed. Use the zipper top stop for zipper repair, replacement, or custom zipper projects where a sturdy stopper is needed.
