THTEN 0.080" String Trimmer Line Compatible with Greenworks 80V 60V 48V 40V 24V GST80320 STB301 ST80L00 ST60B212 ST60B02 BL60L00 STE405 21142 String Trimmer,157 Ft Pre-Cut Twisted Line 9 Pack

What It Is

This is a 0.080-inch diameter, twisted string trimmer line designed for electric string trimmers, including multiple Greenworks models (80V, 60V, 48V, 40V, 24V). It comes as a 9-pack of pre-cut 157-foot total line, intended for residential trimming of grass and light weeds.

Fitment & Compatibility

• Line diameter: 0.080" – check your trimmer’s manual or spool for the maximum line size. Most Greenworks electric trimmers accept 0.080" or smaller; using larger line can damage the spool or motor.
• Compatible Greenworks models: GST80320, STB301, ST80L00, ST60B212, ST60B02, BL60L00, STE405, 21142. Also fits many 24V, 40V, 48V, 60V, and 80V models using 0.080" line.
• Pre-cut length: Each piece is ~17.4 ft (9 pieces total). If your trimmer uses a bump-feed head, these pre-cut lengths work well. For fixed-line heads, you may need to cut them shorter.
• OEM vs aftermarket: This is a third-party replacement, not Greenworks branded. No fitment issues reported, but always verify your trimmer’s line diameter and spool type before buying.

Key Things to Know

• Installation: Easy – just remove the spool, wind the line in the direction indicated on the spool, and reinstall. No tools required.
• Quality: Twisted design reduces tangling and provides decent cutting performance for grass and light weeds. Not ideal for heavy brush or thick woody weeds.
• Durability: Holds up well for residential use but may wear faster than thicker (0.095"+ ) lines on rough terrain. Expect to replace more often if trimming against fences or rocks.
• Common gotcha: Don’t overfill the spool – leave a small gap (about 1/8") between the line and the spool edge to prevent jamming.

Should You Buy It

Yes, if you own a compatible Greenworks electric trimmer and need a reliable, no-fuss 0.080" line for regular lawn trimming. It’s a solid value for the price, with good reviews and easy installation. Skip it if you need a thicker line for heavy-duty clearing or prefer a continuous spool over pre-cut pieces.
