Overview

This spooled trimmer line provides a bulk supply of cutting line for compatible string trimmers and weed eaters. Having extra line on hand means you can reload in the field without cutting a job short. The line is manufactured from commercial-grade nylon for resistance to breaking and fraying.

Key specifications

  • Replacement trimmer line
  • Line diameter: .080”
  • Commercial-grade nylon construction
  • Resistant to fraying and breakage
  • Compatible with bump-feed and fixed-line trimmer heads

Compatibility

This line is compatible with Ryobi 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

With the trimmer powered off, open the spool housing and remove the old spool. Thread the new line through the anchor hole in the spool and wind in the indicated direction, keeping rows tight and parallel. Reassemble the trimmer head and test for proper line advancement.

Common questions

Q: Will this .080 in AC04149A / AC0580PCLA replacement trimmer line fit my RYOBI RY40250 and P20019BTL string trimmers?

Yes, this 12-piece .080 inch replacement line is intended for the listed compatible models, including the RY40250 and P20019BTL. As long as your trimmer uses the AC04149A or AC0580PCLA style pre-cut line setup, these should install and feed correctly.

Q: How do I install these replacement pieces on my RY40ST01K without causing feeding problems?

Make sure the trimmer is powered off and remove the battery or disconnect power before opening the head. Insert each pre-cut line piece fully into the proper eyelet or loading slot until it seats evenly, and replace worn or bent pieces as a set if you notice uneven cutting or vibration.

Q: My RY253SS keeps breaking line quickly—will this .080 line help, and is it the right size?

This product uses .080 inch line, which is the correct size for many homeowner-grade RYOBI trimmers including the RY253SS if it matches the AC04149A / AC0580PCLA system. If your line is breaking often, check for brittle old line, hard contact with fences or concrete, and debris wrapped around the head, since those issues can cause premature wear even with the correct replacement line.

Before you buy — how to verify fitment

  1. Find your trimmer model number. It's usually on a label on the motor housing, battery slot, or lower shaft.
  2. Check spool compatibility. Compare the model number with the compatibility list above.
  3. Verify line gauge. Confirm the line thickness matches what your trimmer head requires by checking your manual or the old spool.
  4. Inspect the spool housing. Make sure the spool diameter, cap, spring post, and feed style match your trimmer head.

Frequently asked questions

How do I know this spool fits my trimmer?

Check your trimmer model number against the compatibility list above. Then verify the line gauge (.065, .080, .095) matches what your trimmer head requires — it's usually printed on the spool cap or in the manual.

Can I rewind a pre-wound spool?

Yes. Once the factory line runs out, you can rewind the spool with bulk trimmer line of the same gauge. Pre-wound spools just save time on the first load.

How often should I replace the spool?

Replace the spool when the line no longer feeds properly, the spring loses tension, or the spool body is cracked. Under normal weekend use, a spool lasts 2–4 refills before the housing wears out.

What gauge trimmer line should I use?

Match the gauge to your trimmer's power: .065" for light-duty electric trimmers, .080" for mid-range cordless, and .095" for gas-powered or heavy-duty models. Using too thick a line can stall the motor.
