Genuine Stihl Bump Knob / Cap for AutoCut C10-2 and C11-2 Mowing Heads.
These mowing heads were fitted to the older FSB-KM “Kombi” grass trimmer attachments.
This is the part of the head you tap on the ground to feed out additional line. It often wears out quicker than any other part of the head and requires replacement.
