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

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.
