SINGER / HUSQVARNA Horizontal Bobbin Case (Ref. 416444401)

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

This original replacement part immediately solves these problems, restoring perfect thread glide to your machine. Its top-loading design makes it easy to insert the bobbin. It is a specific part, designed to fit the rotary system of very popular electronic models and combination machines (sewing and embroidery).

Important notice: Please confirm that the shape of your old bobbin case and the metal tension plate match this image before ordering.
