Stens 380-931 Silver Streak Razor Trimmer Line.080 3 lb. Spool, ea, 1

What It Is

The Stens 380-931 is a 3-pound spool of .080-inch Silver Streak Razor trimmer line, designed for heavy-duty commercial or residential string trimming. It uses a square-edged, serrated profile to cut through thick grass and weeds faster than round line.

Fitment & Compatibility

• Line diameter: .080 inch (2.0 mm). Fits most gas and electric trimmers that accept .080 or .065-.095 line. Check your trimmer’s manual or head for max line diameter.
• Spool size: 3 lb. spool—too large for most trimmer heads. You’ll need to wind it onto a smaller spool or use a bulk-feed head (e.g., Echo Speed-Feed 400, Husqvarna T35, Stihl AutoCut). Not for pre-wound spool replacements.
• Brand cross-reference: Stens #380-931 replaces Oregon 21-931, Rotary 13588, and many OEM bulk line packs.
• What to check: Measure your existing line diameter. Confirm your trimmer head can accept bulk line (not pre-cut). Avoid if your trimmer uses .095 or larger line.

Key Things to Know

• Cutting performance: The Silver Streak Razor’s serrated edges slice through heavy weeds, blackberry vines, and saplings faster than round line. Less “wrapping” around thick growth.
• Installation: Requires winding onto a spool or loading into a bulk-feed head. No pre-cut lengths. Moderate difficulty—use a line winder or follow your head’s loading diagram.
• Durability: .080 is thinner than professional .095 or .105 line, so it wears faster on abrasive surfaces (concrete, rocks). Best for grass and light brush, not edging or heavy debris.
• Gotcha: The 3 lb. spool is heavy and may not fit under some trimmer heads. You may need to transfer line to a smaller spool or cut it into 20-25 ft. lengths.

Should You Buy It

Buy it if you need a high-performance .080 line for thick grass and weeds, and you’re comfortable loading bulk line into your trimmer head. Skip it if you prefer pre-wound spools, need .095+ line for heavy brush, or trim near hard surfaces where thin line wears out fast.
