AC14RL3A String Trimmer Replacement Spool Line with 522994001 Cap for Ryobi One+ 24V, 18V, and 40V Cordless Trimmers, 0.065" Autofeed Replacement Spool- (12 Pack)

What It Is

This is a 12-pack of pre-wound 0.065-inch replacement spools with caps (part #522994001) designed for Ryobi One+ cordless string trimmers. It’s meant for light-to-medium trimming of grass and small weeds on residential lawns.

Fitment & Compatibility

• Voltage compatibility: Fits Ryobi One+ 24V, 18V, and 40V cordless trimmers that use the AC14RL3A spool system.
• Check your cap: The included cap (522994001) must match your trimmer’s cap design. If your original cap uses a different mounting pattern (e.g., 3-tab vs 2-tab), this won’t lock in properly.
• Line size: 0.065-inch diameter – do not use with trimmers requiring 0.080-inch or thicker line, as it will snap under heavier weeds or cause poor autofeed.
• OEM vs aftermarket: This is an aftermarket replacement. It works with genuine Ryobi spools but may have slightly looser fit on some models. Test one spool before loading all 12.

Key Things to Know

• Autofeed reliability: The bump-feed mechanism may require a firmer tap than OEM spools. If line doesn’t advance, ensure the cap is fully seated and clicks.
• No pre-cutting needed: Each spool comes pre-wound with line. Just install the spool, thread the line through the cap eyelets, and trim to 6–8 inches.
• 12-pack value: At ~$1.08 per spool, it’s cheaper than single OEM replacements. But if you only trim once a month, a 12-pack will last years—store in a cool, dry place to prevent line brittleness.
• Cap compatibility gotcha: Some Ryobi 40V models (like the 40V Brushless) use a different cap design. Verify your model number on the cap or manual before buying.

Should You Buy It

Buy this if you have a Ryobi One+ 18V, 24V, or 40V trimmer that uses the AC14RL3A spool and you go through line quickly (e.g., large yard or frequent trimming). Skip it if you need thicker line for heavy weeds, or if your trimmer uses a non-standard cap—test one spool first to confirm fit.
