bernette Invisible Zipper Foot for Dual Feed b77 and b79

With the bernette b77/b79 Invisible Zipper foot there are two diagonal grooves that act as a guide, making zip insertion a breeze compared to the standard method. Located in the sole of the foot, the grooves easily accommodate the zipper coils, which are fed through at the same time as the zipper tape is guided under the foot and sewn.. 

For use on the bernette b77 and b79 sewing machines, with Dual Feed.
