This vintage original Singer Zipper Foot is designed to facilitate the placement of stitching close to a raised edge and is adjustable to either the right or left side of the needle. The hinged feature of this foot insures even feeding over pins, heavy layers of fabric or crossed seams.
Some have even found this particular Zipper Foot useful as a replacement to the original foot often missing from the original Singercraft Fagoter Set.
