Overview
This replacement trimmer line is made from durable nylon to handle extended cutting sessions on grass, weeds, and light brush. Trimmer line wears down and breaks during normal use, and running on a partially empty spool reduces the cutting swath. Keeping fresh line loaded ensures full cutting width and clean edges along driveways and beds.
Key specifications

Compatibility
This line is compatible with Kobalt trimmers as listed above. Verify the line diameter matches your trimmer’s specification to ensure proper fit in the spool housing and guide eyelets.
Installation notes
Remove the spool from the trimmer head and clean out any old line fragments. Wind the new line onto the spool following the directional arrow, keeping the wraps tight and even. Feed the line ends through the eyelets, snap the spool back into the housing, and pull the line to confirm smooth feed.
Common questions
Q: Will this 0.080-in replacement trimmer line fit my Kobalt KST 224B-03 and KST 2580-06, or is it only for certain heads?
Yes, this 12-piece 0.080-inch replacement trimmer line is made for the Kobalt models listed, including KST 224B-03 and KST 2580-06. The key match is both the model number and the 0.080-in line size, so if your trimmer uses the original compatible head for those models, these pieces should fit properly.
Q: I have a Kobalt KST 140XB-06 and KST 1040B-03—do these come pre-cut, and how do I install them?
Yes, these are pre-cut replacement line pieces, so you do not need to measure or wind bulk line onto a spool. To install, power the trimmer off, remove the spool or line carrier per your trimmer’s instructions, pull out the worn pieces, and insert the new 0.080-in line pieces evenly so both sides are seated securely.
Q: My trimmer keeps breaking line quickly on the KST 4024A-03. Is 0.080-in the correct thickness, and how can I make it last longer?
For the KST 4024A-03, 0.080-inch is the correct size for this replacement line, so using the proper diameter helps prevent feeding and cutting issues. To extend line life, avoid striking concrete, chain-link fence, and rocks directly, and check that the line is installed at equal lengths on both sides so the head runs smoothly without extra vibration.
