Stens 380-843 Silver Streak Trimmer Line 1,125-Foot by .105-Inch

What It Is

The Stens 380-843 Silver Streak Trimmer Line is a 1,125-foot bulk spool of .105-inch diameter round trimmer line, designed for commercial-grade string trimmers and edgers requiring a medium-duty line for heavy vegetation, grass, and weeds.

Fitment & Compatibility

• Diameter: .105-inch (2.7mm). Confirm your trimmer head accepts this size—common in professional trimmers (e.g., Stihl, Husqvarna, Echo, Shindaiwa, RedMax) with fixed or bump-feed heads. Not for .080-inch or .095-inch heads.
• Spool size: 1,125 feet. Ensure your trimmer’s line capacity can accommodate bulk loading (most commercial heads hold 50–150 feet per refill). This spool is for multiple refills, not single use.
• OEM vs aftermarket: Stens is an aftermarket brand; compatible with most OEM trimmer heads that accept .105-inch line. No specific brand lock-in, but verify head compatibility (some heads require specific line shapes or diameters).
• Line type: Round, not twisted or serrated. Works in standard heads, but not in heads designed for square or multi-sided line.

Key Things to Know

• Durability: Silver Streak is nylon with a silver coating for reduced friction and heat buildup; lasts longer than standard round line in abrasive conditions, but not as heavy-duty as .130-inch or larger lines.
• Installation: Easy to load manually or with a winding tool. No special tools required, but ensure line is wound evenly to avoid tangling. Bulk spool means you’ll need to cut lengths yourself.
• Common gotchas: .105-inch line may be too thick for some electric or battery trimmers (check manual). Not for brush cutters or heavy clearing—use .130-inch or above for that.
• Value: At 1,125 feet, this is a cost-effective bulk buy for frequent users. Price per foot is ~$0.046, cheaper than pre-cut packs.

Should You Buy It

Buy this if you run a commercial or heavy-use string trimmer that accepts .105-inch line and you need a durable, long-lasting bulk spool for multiple refills. Avoid if your trimmer uses a smaller diameter or if you only trim light grass occasionally—a smaller spool or thinner line would be more practical.
