Brother Bobbin Guide.
This bobbin raiser allows you to use pre-wound or Brother narrower Top Load Bobbins in your Innovis or NX type machine. L-type or TLBs will rattle around in your machine without this spacer.
Machines with built-in thread cutters should only use pre-wound bobbins that have plastic sides.
Cardboard types can damage the cutter mechanism.
Note: If your machine has a sensor that informs of the bobbin thread running low, this function will no longer work.
