Trimmer Part Specification Guide
Compare replacement spool and trimmer part specs side-by-side. Line diameter and shape must match your trimmer head for proper feeding and cutting.
Key specs to check
- Line Diameter — .065" for light grass, .080" for standard trimming, .095" for heavy weeds and brush
- Line Shape — round (quietest), twisted (less drag), star/serrated (sharpest cut)
- Spool Type — pre-wound (drop-in), pre-cut (wind yourself), bulk (by the foot)
Your trimmer's manual specifies the maximum line diameter the head can handle. Using too thick a line overloads the motor; too thin snaps too often.
