Greenworks Spool Cap Replacement Set

This 3-pack replacement spool cap is designed specifically for Greenworks string trimmers using 0.065-inch diameter line and 16-foot spools. Each cap measures approximately the original size (allowing for ±1–3 cm dimensional tolerance) and is made from durable ABS plastic. It fits securely over standard Greenworks spools to protect the fixed line assembly, prevent grass and debris from entering the spool housing, and reduce wear on internal components. Installation requires no tools — simply remove the old cap and snap the new one into place in seconds. Compatible with a wide range of Greenworks models including 21332, 21342, 21222A, 21602, 21062, 21132, 21242, 21282, 21312, 21302, 21362, 21262, 2100202, 2100302, 2100702, STBA40B210, ST40B410, BST4000 and ST40L00, as well as original spool model 29252 and cap model 3411546A-6.
