Ryobi AC14HCA Genuine OEM One+ Replacement Spool Cap for Ryobi One+ 18V, 24V, 40V Cordless Trimmers

What It Is

The Ryobi AC14HCA is a genuine OEM replacement spool cap for Ryobi One+ cordless string trimmers (18V, 24V, and 40V). It holds the trimmer line spool in place and protects the bump-feed mechanism during use.

Fitment & Compatibility

• Works with: All Ryobi One+ 18V, 24V, and 40V cordless trimmers that use the standard bump-feed head (e.g., models P2010, P2011, P2030, P2040, RY40220, RY40440, etc.).
• Check before buying: Ensure your trimmer uses the AC14HCA cap—not the older AC14HCC or AC14HCD versions. Verify by looking at the part number printed on your current cap or checking your trimmer’s manual.
• OEM vs aftermarket: This is genuine Ryobi, so fit is guaranteed. Aftermarket caps may be cheaper but often have looser threads or plastic that cracks faster.
• Measurements: Cap diameter is ~1.5 inches; threads are standard for Ryobi bump-heads. No deck size to check—it’s universal across the One+ lineup.

Key Things to Know

• Quality: OEM plastic is durable and UV-resistant. Aftermarket caps may warp or crack after a season of sun exposure.
• Installation: Takes 30 seconds—push down, turn clockwise to lock. No tools needed. Common gotcha: don’t overtighten; hand-tight is enough.
• Compatibility gotcha: Will not fit Ryobi 2-cycle gas trimmers or older 18V models with the “R” style head (pre-2010). Check your head shape—round vs. star-shaped.
• Price: At ~$6.45, it’s cheap insurance. Buying an aftermarket cap to save $1-2 isn’t worth the risk of poor fit or early failure.

Should You Buy It

If your Ryobi One+ trimmer’s spool cap is cracked, lost, or won’t hold the line, this is the exact replacement you need. It’s a no-brainer at this price—genuine OEM fit, easy install, and proven reliability. Skip the aftermarket knockoffs.
