Part Number: 008 457 7100

This foot is especially well suited for sewing seams in thicker jerseys and sweater knits using an overlock stitch. Couching thicker yarns and cords, and piping
One side of the foot is higher than the other to accommodate the uneven layers encountered when seaming sweater knits or covering and inserting piping (especially corded piping)
The extra space under the foot helps prevent knit fabrics from stretching as they are stitched
The same groove under the foot makes it well suited for making corded piping.

Fits all the old Bernina models from the 530 to the 1630, including the current 1008. 

This foot does not fit modern electronic models, Artista, Aurora, Virtuosa & Activa.
