Chway 0.080-inch DWO1DT802 Replacement String for DEWALT Trimmers – 520 ft Heavy-Duty Square-Twisted Line

Meet the Chway DWO1DT802 replacement string, a 0.080-inch square-twisted line engineered for DEWALT weed eaters. This long-spool option is designed to fit a broad spectrum of DEWALT trimmers, including DCST920B, DCST970B, DCST990B, DCST990H1, and DCST990M1, among others. Consolidating line into a single, versatile reel can simplify upgrades and maintenance across compatible tools, helping you keep outdoor tasks moving smoothly.

The 0.08-inch square-twisted profile is built to bite through mixed terrain—tender grass, stubborn weeds, and light woody growth—while maintaining a steady, controlled cut. The line spins at high speed, producing a decisive cutting action and a satisfying sense of progress as you work along lawn edges, driveways, and along fence lines.

Chway integrates durability into every meter. The material formula is optimized to boost abrasion resistance by roughly 30%, meaning the line can resist wear longer under regular trimming conditions. With a 110-lb tensile strength, the string stays tougher during rapid, high-speed trimming, helping you maintain momentum even when you encounter small obstacles.

In addition to performance, Chway backs the product with professional service and reliable after-sales support. The seller highlights a robust service system with up to two years of coverage, offering assistance or replacements if needed and helping you stay productive in your yard care routine.
