WORX WA0004 replacement spool line twin pack (2 x spools) for Worx grass trimmers

What this is for

If you keep a 20V cordless grass trimmer going through the season, running out of line is one of those small annoyances that slows you down at the worst moment. This WORX WA0004 replacement spool line twin pack is designed to keep spares to hand: it supplies 2 replacement spools, so you can swap and carry on rather than wait around.

On paper, it’s a straightforward “re-fill” style purchase. You’re not upgrading performance here—you’re restoring cutting ability when the line has worn down or snapped. That makes it the sort of buy that’s easy to justify if you use your strimmer regularly.

Key things to know before buying

This is labelled as a replacement spool line twin pack (WA0004) and it’s described as pre-wound cutting line in a double-helix style (DNA2). The listing also points to compatibility with specific Worx grass trimmer models: WG169E, WG163E, WG154E and WG157E.

You’ll want to double-check your current trimmer’s model number before ordering, because spool line systems are usually model-specific. If you’re not sure which Worx WG model you have, it’s worth checking the label on the tool first—otherwise you could end up with a spool that doesn’t fit as expected.

Where it stands out

Two spools in the pack is the practical bit. Instead of buying one spool at a time, you get a spare ready to go. For typical garden tidy-ups—edge work, clearing overgrowth along paths, and quick “get it back under control” sessions—having an extra spool nearby can make the workflow smoother.

The double helix / DNA2 pre-wound line is also a sensible choice for people who want a consistent feed without the faff of winding line manually. That’s especially handy if you’re aiming to do a job quickly after work or at weekends.

What you might not like

It’s a replacement consumable, so expectations should be realistic. This twin pack won’t change the feel of your trimmer, and it’s not aimed at people looking for a different cutting system or experimenting with line types.

Also, because the information provided only lists compatibility with certain WG models, it may not suit other Worx grass trimmers even if they’re similar in name. If your model isn’t one of the WG169E / WG163E / WG154E / WG157E set, you may want to skip this and find the correct spool line for your specific machine.

Everyday use: what the swap looks like

Imagine you’re half-way through trimming an awkward edge by a fence line. The line wears shorter than usual or gives out, leaving you with reduced cutting. Rather than stopping the job, you can replace the spool from the pack, get the trimmer back up to speed, and finish the tidy without waiting for a delivery later.

That’s really the point of this kind of twin pack: it’s about keeping downtime low.

The essentials in plain terms

This product is a pair of replacement spools for Worx grass trimmers that take WA0004 line. It’s supplied as pre-wound DNA2 double helix cutting line, and it’s listed for the WG169E, WG163E, WG154E and WG157E.

If you prioritise being prepared—especially if you do repeat garden maintenance—this kind of twin pack tends to make sense. If you only use your strimmer very occasionally, it might be more than you need right now.

Is it worth it?

A solid pick if you own a compatible Worx WG169E, WG163E, WG154E or WG157E and you want spare spool line ready for the next time your line wears out. Buying the twin pack is particularly sensible if you prefer quick replacements and don’t like interruptions.

It may not be a great match if your trimmer model isn’t one of the listed WG models, or if you were hoping for a performance upgrade rather than a consumable replacement. In that case, it’s better to source the correct spool line for your exact tool.

Quick FAQ

Q: Is this a single spool or two?

It’s supplied as a twin pack: 2 spools in total.

Q: Do I need to check my trimmer model?

Yes—this is listed for specific Worx WG models (WG169E, WG163E, WG154E, WG157E), so matching the model matters.

Q: Is it pre-wound line or loose line?

The description indicates pre-wound DNA2 double helix cutting line, so it’s intended to be a replacement spool rather than manual winding.

Q: What should I expect from a replacement spool line?

You should expect the same basic cutting function to be restored when the existing line has worn down. It’s not designed as an upgrade path—more a “keep trimming” purchase.
