Durable, performance-focused material

Made from PA6 nylon reinforced with 30% glass fiber, this line blends stiffness with heat resistance. The result is a line that holds its shape at high RPMs, helping you maintain a clean edge through thick growth and light brush.

• PA6 nylon with 30% glass fiber for enhanced stiffness
• Improved heat resistance helps reduce deformation during extended use

Auto-feed efficiency and stability

Designed to work smoothly with automatic feed systems, the line uses a snap-fastening cap to lock the spool and reduce vibration. This setup can contribute to steadier cuts and fewer interruptions during longer sessions.

• Seamless auto-feed compatibility with a secure snap-fastening cap
• Potential to improve cutting efficiency by up to 40% in practical use

Pre-wound convenience and quieter performance

Each spool arrives pre-wound for immediate use. The aerodynamic shape reduces air drag, promoting a quieter, cleaner cut and helping your trimmer run more efficiently overall.

• Factory-wound spools for quick setup and tangle-free feeding
• Aerodynamic design minimizes drag for a smoother operation

Size, strength, and real-world durability

The line measures 0.080 inches in diameter and 20 feet in length, with a tensile strength rated over 110 pounds. This combination offers robust cutting power while remaining flexible enough for precise edging and edging details in challenging terrain.

With this 4-pack, you’ll have reliable replacements ready for ongoing yard maintenance. Always verify your model and load the spool correctly to maximize performance and minimize downtime during mowing season.
