Rotary # 12178 Votex Trimmer line Black Commercial Grade #.155 Dia 250' Feet 3 LBS Spool

What It Is

This is a 3-pound spool of #155 diameter (0.155-inch) Votex black trimmer line from Rotary, designed for heavy-duty commercial trimming on large properties, roadside edges, or overgrown grass and weeds. It’s a replacement line for any gas or electric string trimmer that accepts a 0.155” line, not a pre-wound spool.

Fitment & Compatibility

• Line diameter: 0.155 inch (3.9 mm). Must match your trimmer’s maximum line size (check manual or head marking).
• Spool type: Bulk line on a 250-ft spool, not a snap-in cartridge. You’ll need to hand-wind it onto your trimmer’s spool.
• Brand/model: Universal fit for any trimmer that can take .155” line (e.g., Stihl, Echo, Husqvarna, Ryobi, Craftsman).
• OEM vs aftermarket: Aftermarket; works as a direct replacement for OEM line like Oregon, Husqvarna, or Stihl .155” line.
• What to check before buying: (1) Confirm your trimmer’s maximum line diameter (usually stamped on the head or in the manual). (2) Ensure your trimmer’s spool can hold 250 ft of .155” line (most standard spools hold 15–25 ft, so this spool will refill many times). (3) Verify your trimmer uses a bump-feed or fixed-line system—this line works with both.

Key Things to Know

• Quality: Commercial-grade black line is more durable than standard orange or green line; resists breaking on rocks, fences, and thick weeds.
• Installation difficulty: Easy—just cut to length and wind onto your spool. No special tools needed.
• Common gotchas:
  • The .155” diameter may be too thick for some lightweight electric trimmers (most accept up to .095” or .105”). Check before buying.
  • The line is slightly stiffer than consumer-grade line, which can cause feeding issues in older or worn bump-feed heads.
  • 250 ft is a lot of line—store the spool in a dry place to prevent brittleness over time.

Should You Buy It

Buy this if you have a heavy-duty gas trimmer (25cc or larger) or a commercial electric trimmer that accepts .155” line, and you regularly tackle thick weeds, brushy areas, or large properties. It’s overkill for light residential trimming on small lawns—a .095” or .105” line would be easier to feed and cheaper.
