Lucky Seven AC14RL3A Replacement Trimmer Spools for Ryobi One+ 0.065" Autofeed — 12-Pack, Pre-Wound with Caps

Lucky Seven AC14RL3A replacement spool is a pre-wound, 0.065" autofeed trimmer line kit with compatible caps for Ryobi One+ 18V, 24V and 40V cordless trimmers.

This 12-piece aftermarket kit includes ten factory-wound AC14RL3A spools and two replacement caps (compatible with part numbers such as 522994001 and 3411546-7G). The spools use a twisted copolymer nylon blend with UV protection, are sized at .065" diameter and approximately 11 feet per spool, and are designed for easy snap-in installation and fast autofeed operation. It’s built to make mid-job refills quicker while matching the fit for many Ryobi One+ models.

Will these spools fit my Ryobi One+ cordless trimmer?

Yes — the spools are built to the AC14RL3A profile and the kit includes caps that replace common OEM part numbers. They are intended for Ryobi One+ trimmers across the 18V, 24V and 40V lines that accept the AC14RL3A spool.

• Compatible with AC14RL3A spool specification and cap numbers like 522994001 and 3411546-7G.
• Works with many Ryobi One+ 18V, 24V and 40V cordless trimmer models.
• Replaces obsolete OEM references such as 993373001 and HM3411546BG in many cases.

How easy is installation and on-the-job refilling?

Installation is tool-free: the pre-wound spools snap into the head and the included caps press on securely. Clear winding direction and string insertion guidance are printed on the spool shell to help you add new string quickly if you need to refill during a job.

• Factory-wound spools eliminate hand-winding time.
• Snap-in design requires no nuts, bolts, or special tools.
• Printed refill instructions on each spool speed up mid-job replacements.

What cutting performance and durability can I expect?

The .065" twisted copolymer construction balances flexibility and cutting ability for lawn grasses and tender weeds. UV-resistant material helps the line withstand sunlight exposure for longer service life, though it’s best for trimming lighter vegetation rather than thick woody growth.

• 0.065" diameter provides good reach and cleaner trim on grass and soft weeds.
• Approximately 11 feet of line per spool offers extended trimming before replacement.
• UV-protected resin improves longevity when stored or used outdoors.

Are there safety or usage limitations I should know about?

These spools are designed for grass and softer weeds; dense brush or woody plants can overload the line and are better handled with a blade attachment. Because spools are designed to feed automatically, maintain distance from bystanders and wear eye and hand protection when operating any trimmer.

• Not recommended for heavy brush or thick woody stems.
• Use protective eyewear and follow centrifugal-safety precautions.
• If line breaks often, switch to a heavier-duty cutting blade or thicker line.

This Lucky Seven pack suits those who prefer ready-to-install, autofeed spools to save time on routine maintenance, extend outdoor durability with UV-resistant line, and keep a supply of caps and spools on hand for frequent trimming sessions.
