8Pcs Wear-Resistant Spool Caps

Precision-engineered spool caps sized at 84 mm × 39 mm, made from industrial-grade ABS plastic for consistent durability and dimensional stability. Compatible exclusively with Worx trimmer models WG184, WG190, WG191 and WG168, they replace the original WA0037 cover to restore full spool protection and line management. The ABS formulation delivers strong resistance to abrasion from grass, gravel and soil contact, while maintaining flexibility to absorb minor impacts without cracking. Installation requires no disassembly — just align and press firmly into place. Supplied as a set of eight, enabling proactive replacement before failure and reducing downtime during peak gardening seasons.
