PEHUAP KST-120X Weed Eater Spool Replacement - 0.065 in x 20 ft - Kobalt 40V Compatible Dual-Line - 6-Pack

PEHUAP KST-120X: A reliable spool replacement for Kobalt 40V trimmers

Keep your lawn maintenance routines smooth with the PEHUAP KST-120X Weed Eater String Spool Replacement. It is engineered to work seamlessly with Kobalt 40V trimmers, including models KST 120X, KST 120X-06, and KST 2040-06. If your trimmer head relies on a pre-wound spool, this option provides an easy drop-in replacement that minimizes downtime and helps you finish edges, borders, and patches of dense growth with confidence.

Beyond compatibility, the spool emphasizes durable construction and dependable line feeding. The housing is built from high-impact ABS, and the line itself uses premium nylon. The combination yields a line that resists wear while staying flexible enough to absorb impacts from stones and tough grass, reducing the risk of frequent snap-offs. This design aims to support steady cutting performance across a range of yard tasks without overtaxing the tool.
