This genuine Stihl spool insert is the internal reel for the AutoCut 25-2 trimmer head, used on Stihl grass trimmers and brushcutters. It is moulded from durable, impact?resistant plastic to handle regular use and exposure to debris. The insert holds and guides the cutting line so it feeds smoothly and consistently, helping the head bump and release line as designed.
