LikeLion 20155A Pre-Cut Red Trimmer Line, 0.155-Inch x 21-Inch, 10 Count, for Walk Behind String Mowers & Gas Trimmers, Heavy Duty Commercial Grade

What It Is

The LikeLion 20155A is a pre-cut, heavy-duty commercial-grade trimmer line designed for walk-behind string mowers and gas trimmers. Its 0.155-inch diameter and 21-inch length make it ideal for edging and trimming in tight spaces where spool-fed lines aren’t practical.

Fitment & Compatibility

Check three things before buying: line diameter (0.155 in. fits most standard gas trimmers and string mowers; verify your machine’s max line size), length (21 in. must match your trimmer head’s loading slot or anchor points), and head type (pre-cut line works with bump-feed or fixed-head systems that accept individual strands—not spool-only heads). This is an aftermarket replacement; it has no OEM-specific lock-in, but confirm your deck or trimmer model accepts 0.155 in. line. For walk-behind mowers, measure the cutting swath (typically 12–22 in.) to ensure the 21-in. length won’t overhang or undercut.

Key Things to Know

• Quality: Commercial-grade nylon resists fraying and snapping on heavy weeds, but the 0.155-in. diameter is thinner than standard 0.080–0.095 in. lines—it’s better for precision trimming than thick brush.
• Installation: Pre-cut strands are easier than spool winding: simply insert each end into the head’s slots and secure. No cutting or measuring required.
• Gotcha: The 10-count pack covers about 2–4 refills per season for a typical walk-behind mower; if you trim aggressively, plan to reorder sooner.
• Compatibility: Not for electric trimmers with proprietary line sizes (e.g., 0.065 in.)—verify your machine’s manual first.

Should You Buy It

Buy this if you need a quick, no-spool replacement for a walk-behind string mower or gas trimmer that accepts 0.155-in. line, and you want commercial-grade durability for regular edging. Skip it if your machine requires a thicker line (0.080 in. or more) or if you prefer spool-fed convenience.
