Kousika replacement spools for WORX string trimmers — 12 pre-wound 10ft 0.065" spools + 2 caps, quick-install autofeed

Kousika replacement spools (WA0010/WA0004) with pre-wound 10 ft of 0.065" nylon line and two WA6531 caps let you quickly restore WORX WG-series string trimmers to reliable cutting performance.

These refill spools are made to fit many WORX cordless trimmers and edgers, offering a ready-to-install alternative to OEM parts. Each spool arrives pre-wound with 10 feet of durable polyamide nylon line, and the set includes two replacement caps so you can finish more than a season of trimming without hunting for parts. The design focuses on quick installation, consistent feed, and materials that resist snapping under normal yard conditions.

Which WORX models will these Kousika spools fit?

These spools are compatible with a wide range of WORX WG model trimmers and edgers, covering older and current series versions. Check your trimmer’s spool part number or model listing to confirm compatibility before purchasing.

• Compatible with WG122, WG150–WG157, WG160 series, WG162, WG163 variants, WG165–WG166, WG170 series, WG175 and WG180.
• Fits spool models WA0010 and WA0004, and cap model WA6531 / 50006531.
• Works with WORX GT cordless trimmer/edger platforms that accept these parts.

How easy is it to install and use the replacement spools?

Installation is straightforward: remove the old spool and snap the Kousika replacement into place, then secure the included cap. Pre-wound line eliminates manual spooling, saving time and reducing installation errors for homeowners and landscapers alike.

• Pre-wound 10 ft of 0.065" line per spool—ready to install.
• Snap-in ABS autofeed spool design for quick replacement.
• Two caps included to restore secure housing after installation.

What are the material and performance features of these spools?

The spools are injection-molded from durable ABS for impact resistance, while the cutting line uses polyamide nylon for strength and flex. Together these materials deliver a longer life span than brittle alternatives and help maintain consistent feeding under regular trimming loads.

• ABS autofeed spool reduces cracking and warping.
• 0.065" polyamide nylon line offers balanced tensile strength and flexibility.
• Pre-wound length reduces downtime and installation mistakes.

How many trims will a 12-spool pack cover and what’s included?

This value pack supplies twelve pre-wound spools plus two caps, providing enough line and hardware for many maintenance sessions. Exact coverage depends on how often you bump-feed or the thickness of vegetation, but the bundle is designed to minimize repeat purchases.

• 12 pre-wound spools × 10 ft each = 120 ft of trimming line total.
• 2 replacement caps (WA6531/WA0010 cap parts) included for spool housing.
• Pack aimed to cover multiple trimming cycles or share spools across tools.

Who is this for: Homeowners, gardeners, and small-property landscapers who use compatible WORX cordless trimmers and want a convenient, affordable supply of factory-fit replacement spools. If you need quick installs, consistent line feed, and a bulk refill option that matches WA0010/WA0004 spool fittings, this Kousika kit gives an economical way to keep your trimmer ready without waiting for OEM parts.
