A ANLEOLIFE .170" Heavy-Duty Dual-Core Trimmer Line - 367 ft Spool, Square Profile, Extra-Tough

The A ANLEOLIFE .170" Heavy Duty Dual-Core Trimmer Line is a robust, dual-core square-profile cutting cord designed for walk-behind and heavy brush trimming, supplying 367 feet of extra-thick line for demanding edge and field work.

When you need a replacement line that stands up to thick stems, dense brush, and high-load trimming sessions, this extra-gauge .170" spool focuses on power and durability instead of maximum length. The clear outer sheath minimizes welding and abrasion while the black inner core adds tensile strength, giving a balance of wear resistance and break protection tailored for fixed-line heads and DR walk-behind mowers. This spool suits contractors, landowners, and anyone using high-output gas or battery heads that accept .170-rated cord.

How does this dual-core construction improve durability?

The two-layer design separates abrasion resistance from core strength: the outer clear layer reduces welding and scuffing on metal cutters, while the darker inner core resists snapping under heavy load. The square profile also increases cutting edges, letting the cord bite through thicker stems and coarse grasses more effectively than round lines.

• Clear outer layer lowers heat and welding during reloads
• Black inner core improves tensile strength and break resistance
• Square cross-section creates sharper cutting surfaces
• Engineered for short, high-load trimming rather than long run lengths

Which machines and heads are compatible with this .170" line?

This heavy-duty line fits heads and fixed-line systems rated for .170" cord, including many walk-behind DR string mowers and high-capacity heads from well-known brands. It is not intended for light-duty consumer trimmers or heads that explicitly limit diameter below .170".

• Compatible with DR walk-behind and fixed-line heads
• Works with many high-output heads from Husqvarna, Echo, Stihl, and others
• Suitable for gas or high-capacity cordless string mowers
• Not recommended for small consumer heads or sub-.170" rated spools

What tasks is this spool best suited for in the field?

This spool shines when clearing overgrown property edges, ditch lines, fence rows, and rough growth where thick stems and woody material are common. The emphasis is on power and cut quality over total line length, making it ideal for short, intensive clearing passes or for professionals who reload frequently during heavy-duty jobs.

• Cutting tall coarse grass and thick stems along field borders
• Clearing ditch lines, fence rows, and overgrown edges
• Use in walk-behind mowers for consistent, heavy contact work
• Designed for pro and landowner workloads rather than lightweight yard touch-ups

How much line do you get and what does the spool support?

The spool contains 367 feet of .170" diameter line and weighs roughly 5 pounds, giving you an extra-thick gauge optimized for strength. This quantity is tuned for jobs where thicker cord and fewer reloads per head engagement are preferred, rather than maximizing total feet for light trimming.

• 367 ft spool length at .170" diameter
• 5 lb large-gauge spool for heavy-duty use
• Built-in cutter on compatible heads helps reload efficiently
• Designed for short, high-load sessions and quick reloading

Who is this for? The A ANLEOLIFE .170" Heavy Duty Dual-Core Trimmer Line is aimed at landscaping professionals, property owners with large overgrown acreage, and users of walk-behind or high-output trimmer heads who need a thick, reliable cord to tackle coarse growth and woody stems. If your work demands robust cutting performance from a cord that resists welding and snapping under pressure, this spool delivers targeted strength; if you primarily run lightweight consumer trimmers or prioritize maximum line length, consider a smaller-diameter option instead.
