If you often shorten separable (open end) zippers, this tool removes completely the spiral chain and its sewing thread from both zipper tapes of sewn spiral zippers in seconds. As a result you obtain a neat top tape extension, which allows you to process further the zipper more easily. Application video

The tool is only available for 4 to 6.7 mm wide spiral chains. Each chain width requires a separate tool. The tool is not suitable for woven spiral zippers.

The name "Gappy" comes from the gapping process in the industrial zipper production. (Privacy notice: The video at the following link opens on the YouTube website.) external A gapping tool punches gaps in the endless zipper chain, before it is cut into finished lengths. Our "Gappy" tool does not punch gaps, but it has the same purpose: It removes the zipper chain from the zipper tape.
