Bobbin Case "L"

Style "L" bobbin case includes bobbin case brake spring to reduce bobbin overspin. Save time adjusting the bobbin tension for different threads by purchasing a separate bobbin case for common threads or bobbin types. Set the tension on the bobbin case to match the thread or the bobbin style, and pop in the bobbin case and go! If using Magna Glide bobbins, remove the brake spring. This part fits all generation models.
