This presser foot is used for sewing the very edge of the zipper, and sewing piping and D-ring that has more height than the fabrics. Since the width of the narrow zipper foot is small, the operator can easily observe the material during sewing. It has two (right and left) recesses on its undersurface, you can sew higher portions of the material while avoiding those portions. Both the right and left sides of the zipper can be sewn only by changing the position of the needle baseline. The mounting portion of this presser foot is placed at its center, so the stable feed of the material is ensured.
