Overview

Designed as a plug-and-trim aftermarket replacement, this pre-wound spool fits directly into the trimmer head without any custom winding. Factory spools eventually run out, and hand-winding bulk line can be time-consuming and prone to tangles. This replacement spool provides properly wound line that feeds smoothly from the first tap.

Key specifications

  • Pre-wound replacement trimmer spool
  • Direct-fit for listed trimmer models
  • Bump-feed compatible winding pattern

Compatibility

This spool is designed for Homelite string trimmers as listed above. Confirm the spool part number, line diameter, and trimmer model before ordering to ensure a proper fit.

Installation notes

Disconnect the battery or unplug the trimmer. Remove the bump knob or spool cover by pressing the release tabs. Lift out the used spool, insert the new one with the line routed through the exit holes, and replace the cover. Pull the line to confirm smooth feed before starting.

Common questions

Q: Will this AC41RL3 / AC41RDLB 31104178G dual replacement spool fit my Homelite UT41112B 13-inch 4 Amp string trimmer?

Yes, this spool is made to fit the Homelite UT41112B, and it also matches UT41113, UT41112, and UT41120 models listed for the 13-inch 4 Amp trimmers. It is also compatible with Portland trimmers that use spool numbers 62567, 62338, and 63387, but it’s always smart to match your original spool number before installing.

Q: How do I install this dual replacement spool on a Homelite UT41120 without tangling the line?

Start by unplugging the trimmer, removing the spool cap, and lifting out the old spool. Drop the new dual spool in with the line ends fed through the eyelets, make sure the line isn’t crossed underneath, then reinstall the cap securely so the spool can advance correctly.

Q: Is this 31104178G dual spool pre-wound, and what kind of trimming is it best suited for?

This style of replacement spool is intended for standard grass and light weed trimming on the compatible Homelite and Portland electric trimmers. For best performance, avoid forcing it into heavy woody stems or dragging the line against concrete edges, since that wears the line faster and can reduce feed performance.

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.
