Bernina Bobbin Case - Black Latch: For Bobbinwork - For CB Shuttle Models (See info for compatible machines)

This specialised bobbin case is used when sewing with heavyweight or specialty threads on the bobbin, such as topstitch or cordonnet thread. These threads require a looser tension than regular thread in order to move freely through the bobbin and form stitches. The tension on this case is also easily adjusted by turning the small screw on the side. Rather than having to change the tension setting on the standard bobbin case - and then having to readjust it afterwards to achieve the normal setting again - use the Black Latch Bobbin Case. 

Please note: It is recommended to only use this case for these special techniques, and to switch back to your standard bobbin case for regular sewing. The black latch serves as a reminder that this bobbin case is not set for normal sewing.

This is a genuine Bernina product - it has been precisely engineered and manufactured specifically for your machine's hook system. 

This bobbin case is suitable for the following machine categories:

  A (910 - 933 / 1000 - 1530)    |    B
