QPQ 21-380B-0.080 in. Round String Trimmer Line, Green,416 ft. Bulk Donut, Professional Weed Wacker Line Replacement，Compatible for DW Stihl Ryobi Greenworks

What It Is

This is a 0.080-inch round trimmer line in a 416-foot bulk donut spool, designed for professional-grade weed trimming on gas and electric string trimmers. It’s suited for heavy-duty cutting of thick grass and light brush.

Fitment & Compatibility

• Line diameter: 0.080 in. – fits trimmers that accept this size (common for mid-range to heavy-duty models). Check your trimmer’s manual or head for max line diameter.
• Bulk spool: Not pre-wound. You must cut and load it into your trimmer head manually. Works with bump-feed, fixed-line, or quick-load heads.
• Brands: Compatible with DW, Stihl, Ryobi, Greenworks, and most trimmers using 0.080 in. line. Not for trimmers that require pre-cut strips or specific shapes (e.g., star/quad).
• OEM vs aftermarket: Aftermarket replacement. No fit issues if trimmer accepts 0.080 in. round line.

Key Things to Know

• Durability: QPQ-treated line resists fraying and breaking better than standard round line. Good for hard surfaces (sidewalks, driveways) but not for heavy brush.
• Installation: Easy – cut to length (usually 10-20 ft per load) and wind into head. No tools needed. Avoid overfilling.
• Gotcha: 0.080 in. is thicker than standard 0.065 or 0.095 in. line. If your trimmer head is designed for 0.095 in., this will rattle and cut poorly. Verify your head’s line diameter range first.
• Length: 416 ft – a bulk buy. Lasts many refills for frequent users. Store in a dry place to prevent brittleness.

Should You Buy It

Buy this if you have a gas or electric trimmer that accepts 0.080 in. line and want a tough, fray-resistant option for regular lawn maintenance and edging. It’s a good value for pros or heavy users, but skip it if your trimmer needs a different diameter or pre-shaped line.
