Eventronic Trimmer Spool 0.065 in Auto-Feed, Greenworks Compatible – 3-Pack

Overview

The Eventronic trimmer spool is a 0.065-inch single-line replacement crafted to fit a broad range of Greenworks cordless trimmers. This 3-pack arrives with pre-assembled spools, so you can start mowing sooner without winding new line. The compact design features a 2.16-inch spool width, a 0.78-inch height, and a 0.39-inch center bore for smooth mounting on compatible tools.

In use, you may notice a steady feed and a clean cut as the line advances. The upgraded nylon polyamide construction offers flexibility and resilience, helping the line cushion against impact while you work along edges or through light brush. This combination aims to support efficient trimming sessions with less downtime between replacements.

Compatibility and setup

Compatibility matters. Please verify your trimmer model and confirm that it matches one of the supported models listed in the product notes to avoid incorrect purchases. The spool is designed for 0.065" single-line use and works with many Greenworks cordless trimmers, including models such as 21342, ST24B215, STBA24B210, STBL24B210, ST24B05, ST24B217, STBL24B410, 21332, STBL40B501, ST40B05, ST40L213, 2100302, and 21302. If your model differs, this spool may not fit your tool.

Materials and engineering

The spool uses upgraded nylon polyamide with a tensile strength exceeding 110 pounds. The design is pliable yet strong, allowing the line to stretch slightly and cushion impacts during cutting, which can help maintain consistent performance across repetitive tasks.
