Why customers choose Cera Garden

Meet the YWTESCH 4 Pack Spool Cap, a purpose-built replacement designed for Greenworks cordless weed whackers. When you need a fast, reliable cap swap, this set offers a durable build, precise compatibility, and ready availability to help you keep trimming without downtime.

Compatibility matters: these caps are designed to pair with Greenworks models 2101602, 2101602A, STBA40B210, ST40B410, BST4000 and are intended for use with 0.065" dual line auto-feed spools. The result is a secure fit that helps protect the line and keeps the spool aligned as you work along sidewalks, fences, and overgrown edges.

Upgraded durability for fast spins

The cap is constructed from PA6 (nylon) with 30% glass fiber. This blend increases hardness, abrasion resistance, and heat tolerance, making it well-suited for high-speed trimming compared with standard ABS parts. The reinforced material helps the cap hold its shape under demanding use, contributing to longer wear life for the cap itself and steadier line management.

  • Non-slip design maintains a secure cap during operation.
  • Raised circular surface adds friction to reduce surface wear and extend life.
  • Overall size: 2.95 inches in diameter and 1.25 inches high for a stable fit.

Smart design for real-world use

In practice, a dependable spool cap translates to fewer interruptions and smoother feeding as you navigate around turns, edging, and dense growth. The 4-pack provides ready replacements so you can swap in seconds, keeping your trimmer ready for the next pass.

  • Includes 4 caps for quick swaps across compatible Greenworks setups.
  • Backed by reliable after-sales support to resolve fit questions within 24 hours.

What you get and how to use it

This replacement cap mirrors typical dimensions—2.95" diameter and 1.25" height—designed to fit with compatible spools. If you’re unsure about fit, share your trimmer model and spool type, and we’ll help verify compatibility. This product is a replacement component to complement your system, not a guaranteed performance upgrade, but it is built to withstand fast spins and to help protect the line and spool during operation.
