8Pcs Tough ABS Trimmer Spool Cap

These spool caps measure 84 mm in diameter and 39 mm in height, and are manufactured from high-strength ABS polymer known for its balanced toughness and resistance to abrasion and impact. They serve as direct replacements for the original WA0037 cap used on Worx cordless and electric string trimmers including WG184, WG190, WG191 and WG168. Their primary function is to shield the spool and wound line from debris, UV degradation, and mechanical damage — contributing to consistent line feed and safer handling. Installation is fully manual and immediate: align and press until seated. Each package contains eight identical caps, supporting extended equipment uptime and planned maintenance cycles.
