Stens 380-924 Silver Streak Razor Trimmer Line.105 1 lb. Donut, ea, 1

What It Is

The Stens 380-924 Silver Streak Razor Trimmer Line is a .105-inch diameter, 1-pound donut spool of trimmer line designed for heavy-duty commercial or residential string trimmers. It uses a squared, razor-edge profile for aggressive cutting through thick grass, weeds, and light brush.

Fitment & Compatibility

• Diameter: .105 inch (2.67 mm). Fits trimmers that accept .095–.110 line; do not use in trimmers requiring .080 or smaller.
• Spool type: Donut (center hole), 1 lb. Not pre-wound—you must cut and load manually.
• Machine fit: Universal for gas or electric trimmers with a spool that accepts .105 line. Check your trimmer’s manual or current line size; avoid oversized spools if your bump head is small.
• OEM vs aftermarket: Aftermarket replacement for brands like Echo, Stihl, Husqvarna, Ryobi, etc. No direct OEM cross-reference—verify fit by line diameter and spool capacity only.

Key Things to Know

• Cutting performance: The razor edge cuts faster than round line but dulls faster in rocky or abrasive terrain. Expect to replace more often than standard round line.
• Installation: Moderate difficulty. You must cut the line to length (typically 12–15 feet per side) and wind tightly on your spool. Avoid overlapping or twisting.
• Common gotcha: The .105 line is thick—some trimmer heads may not hold enough length for full bump-feed cycles. If your head is small, you’ll reload more often.
• Durability: Good for normal grass/weeds; not for heavy brush or edging against concrete (will wear quickly).

Should You Buy It

Buy this if you need a fast-cutting, aggressive line for thick grass and weeds, and you don’t mind more frequent line changes in tough conditions. Skip it if your trimmer uses .080 or smaller line, or if you need a line that lasts through heavy abuse near hard surfaces.
