Singer Horizontal Bobbin Case (Ref. 359841-001 / 359841-900)

The horizontal bobbin case is the essential part where the bobbin is inserted, ensuring perfect control of the lower thread tension during sewing. When this plastic holder wears out — such as small scratches or nicks caused by a broken needle hitting it — the thread begins to snag, resulting in irregular and skipped stitches.

This original replacement part immediately solves these problems. Its top-loading (horizontal) design makes threading easy. It is a capsule with a very specific internal shape, designed exclusively for the system that uses SureFit bobbins (bobbins that only fit in a certain way).

Important notice: The shape of this capsule is exclusive to the Inspiration series. Please confirm that the shape of your old capsule and the metal tension plate match this image before ordering.
