This is a single compression spring for a string trimmer. This spring is made of metal and can lose tension over time, in which case it will need to be replaced. To access this part, you will need to remove the head of the trimmer, which will expose a bolt, which will need to be removed so the compression spring can be slid off the shaft using your fingers. This is an OEM part sourced directly from the manufacturer.
