Brother Bobby Pin

Use this Brother adapter with Class-L bobbins on a machine that normally uses Class-15 bobbins (e.g.: machine calls for SA156/Class-15 bobbins and the pre-wounds you are using are Class-L).  Comes in handy when pre-wound bobbins have the thread you need but are on the wrong class/size bobbin. This bobbin center pin (spacer) can be used with either the standard or alternate bobbin case. Use this bobbin center pin (spacer) for better thread flow, bobbin stability, and to provide the correct height for pre-wound bobbins in the bobbin case. Adapter has special coating on the bottom so glides very smoothly. Adapter is shown quite enlarged for detail. Actual size is approximately the same diameter as a bobbin.
