Whit these accessories, wire is guided properly and it is not scraped during the unwinding from the bobbin in the bell. It is just in contact with a bearing and two polished stainless steel flanges.
Manual brake adjustment with a screw on a special felt.
Mechanical stop on the bell (useful for thick wires).
