105 Trimmer Line, 105 Weed Eater String, 105 String Trimmer Line, 105 Weed Eater Line, Commercial Square 105 Weed Wacker String- 0.105""-628Ft-3Lb for String Trimmer Weed Trimmer, Orange

What It Is

This is a 0.105-inch diameter, square-shaped trimmer line designed for heavy-duty weed trimming. It’s best suited for commercial-grade string trimmers and large residential mowers that need a thicker, durable line for thick grass, brush, and overgrown weeds.

Fitment & Compatibility

• Line diameter: 0.105 inches (2.67 mm) – fits most trimmer heads that accept this gauge, but check your trimmer’s manual for max line size. Common for brands like Echo, Stihl, Husqvarna, Ryobi, and Craftsman.
• Shape: Square profile – cuts more aggressively than round line; compatible with bump-feed, fixed-line, and automatic-feed heads.
• Length: 628 feet total (3 lbs) – enough for many refills. Measure your trimmer head’s line capacity (e.g., 15-30 ft per spool) to ensure it’s not too much for your head.
• OEM vs aftermarket: This is a commercial-grade aftermarket line. Works fine in most OEM heads, but some brand-specific heads (e.g., SpeedFeed) may require trimming to fit.

Before buying: Confirm your trimmer’s required line diameter (check the manual or existing line). If your head is a bump-feed type, ensure the square shape feeds smoothly (some round-only heads may jam). Also verify the spool or head can hold the full length without overloading.

Key Things to Know

• Quality: 0.105-inch square line is stiffer and lasts longer than standard 0.080-0.095 inch line, but it’s heavier and may strain smaller trimmers (under 30cc engines). Best for mid-to-large trimmers.
• Installation: Easy to cut and load, but the square shape can bind in some heads if not wound tightly. Soak the line in water for 15 minutes before loading to reduce brittleness.
• Common gotchas: This line is thicker than most residential trimmers accept – check your trimmer’s max line size to avoid damaging the head or engine. If your trimmer has a fixed-line head, you’ll need to cut pre-measured lengths (e.g., 10-12 inches per side).
• Value: 628 feet for $26.99 is competitive for commercial line. Expect 2-3 times longer life than round line of similar gauge.

Should You Buy It

Buy this if you have a mid-to-large trimmer (30cc or higher) and need a heavy-duty line for thick weeds, brush, or commercial use. It’s not ideal for small electric trimmers or light residential trimming – stick with 0.080-0.095 inch line for those.
