Overview
Keep your string trimmer ready for action with this pre-wound replacement spool. It is built to the same dimensions as the OEM spool, so it drops right into the trimmer head with no modifications. Aftermarket spools provide the same cutting performance as factory originals at a better value.
Key specifications
- Pre-wound replacement trimmer spool

Compatibility
This spool is designed for Hyper Tough string trimmers as listed above. Confirm the spool part number, line diameter, and trimmer model before ordering to ensure a proper fit.
Installation notes
Remove the spool cover from the trimmer head. Extract the old spool and clean out any grass or debris. Insert the new pre-wound spool, feed the line ends through the guide holes, and reattach the cover. Verify the line extends the correct length before trimming.
Common questions
Q: Will this HT-21-401-002-04 / HT10-401-002-01 spool fit my Hyper Tough HT18-401-004-01 13-inch 4.6-Amp electric string trimmer?
Yes, this spool is intended to fit the Hyper Tough HT18-401-004-01 13-inch 4.6-Amp electric string trimmer. It is also listed as compatible with Worx WG116 and WG119 electric trimmer/edger models, but it’s always smart to match the spool number on your original part before installing.
Q: Can I use this spool on a Worx WG119 12-inch 4.0 Amp trimmer/edger, and do I need to change the cap too?
This spool is compatible with the Worx WG119 and WG116 models listed, as long as your existing spool cap and housing are not cracked or excessively worn. In most cases you can reuse your current cap, but if the line does not feed smoothly after installation, inspect the cap tabs and spool holder for wear.
Q: What’s the correct way to install this replacement spool so the line feeds properly?
Unplug the trimmer first, then remove the spool cap, lift out the old spool, and clear any grass or debris from the housing before inserting the new one. Make sure the line end is threaded through the eyelet correctly and the spool sits fully in place; if it’s installed backwards or the line is pinched, it may not advance smoothly during use.
