105 Trimmer Line Square .105 Weed Eater String with High Strength Inner Core 5 LB Commercial Weed Wacker String .105-inch Trimmer Line Spool 1038 Ft Fits Most of Trimmer Mower

What It Is

This is a 5-pound spool of .105-inch square trimmer line with a high-strength inner core, designed for heavy-duty commercial or residential weed whacking. It fits most gas and electric trimmers that accept .105-inch line, offering 1,038 feet of cutting cord for sustained use.

Fitment & Compatibility

Before buying, confirm your trimmer’s line diameter requirement—.105 inch is thicker than standard .080 or .095 line. Check your owner’s manual or the trimmer head for a stamped diameter spec. This line is not universal: it won’t fit trimmers that only accept smaller diameters (e.g., .065 or .080) or those with proprietary spool systems (e.g., SpeedFeed, Tap-N-Go). It works with most brands (Echo, Husqvarna, Stihl, Ryobi, etc.) if the head is compatible with bulk .105 line. Measure your existing line with calipers if unsure. It is aftermarket, not OEM, so no brand-specific guarantee.

Key Things to Know

• Strength vs. flexibility: The inner core boosts durability for thick weeds/brush, but the square shape can be less forgiving on lightweight grass—expect more vibration at high RPMs.
• Installation: You load this from a bulk spool, not a pre-wound cartridge. You’ll need to cut lengths and wind manually—allow 10-15 minutes if new to this.
• Common gotcha: Overloading the trimmer head with too much line can cause jamming or poor feed. Stick to 20-30 feet per load (check head capacity).
• Durability: Rated for commercial use, but .105 is still a medium-heavy line—not ideal for hitting rocks or concrete edges repeatedly (will still fray).

Should You Buy It

Buy this if you have a compatible trimmer, need long runtime (1,038 feet), and regularly cut heavy weeds or overgrown areas. Skip it if your trimmer uses smaller line or you want easy pre-wound spools—this requires manual winding and may not feed smoothly in all heads.
