The Duro-Cut Replacement Line with a .120-inch diameter is a serrated precut line intended for use with heavy-duty trimmer heads and brushcutters designed to handle thicker grass, weeds, and brush. These precut lines are typically used for more demanding tasks and provide efficient cutting performance.
While it is essential to consult your specific trimmer's owner's manual or contact the manufacturer for compatibility confirmation, the .120-inch diameter Duro-Cut Replacement Line is generally compatible with trimmer heads that can accommodate this thicker line size. This includes several heavy-duty trimmer models and brushcutters across various brands.
If you are using a Stihl trimmer or brushcutter, it is advisable to consult your trimmer's documentation or contact Stihl's customer support to ensure the .120-inch Duro-Cut serrated precut line is suitable for your specific model. The compatibility may vary depending on the trimmer head you are using and the trimmer's model and version.
