Bobbin Cover for Singer (Ref. 416428301)

The bobbin cover is the clear acrylic cover plate that slides to seal the lower bobbin compartment in the sewing machine. Its transparency allows for a quick check of the remaining thread, preventing projects from running out of thread mid-seam, which is especially useful in high-speed machines.

In addition to visibility, this small flat plate has the crucial function of holding the bobbin in place (preventing it from jumping out due to vibration) and preventing dust and lint from accumulating in the rotary hook area. As it is made of plastic and subject to frequent removal or impact from broken needles, it can wear out, scratch, or get lost, and its immediate replacement is essential to ensure smooth fabric feeding.
