RYOBI 2-in-1 Fixed Line and Bladed Head AC052N1 - Accessory for Auto Feed String Trimmers

What It Is

The RYOBI 2-in-1 Fixed Line and Bladed Head AC052N1 is a replacement trimmer head for Ryobi auto-feed string trimmers. It lets you switch between standard trimming line and a plastic blade for clearing heavier weeds or light brush without changing heads.

Fitment & Compatibility

• Brand and model fit: Designed exclusively for Ryobi auto-feed trimmers (models like RY253SS, RY25400, RY255SS, RY2600, and similar). Not compatible with manual-feed or universal trimmers.
• Check your trimmer’s shaft type: This head fits only straight-shaft trimmers with an 8mm (5/16") drive hole. Curved-shaft models require a different part.
• OEM vs aftermarket: This is an OEM Ryobi part (AC052N1), so fit is guaranteed on compatible models. Aftermarket knockoffs may not lock in correctly.
• Measure before buying: Verify your current head’s drive hole diameter and shaft type. If your model uses a 10mm hole or a curved shaft, this won’t work.

Key Things to Know

• Installation is straightforward: Remove the old head, align the drive hole, and hand-tighten the retaining nut. No tools needed, but wear gloves—the blade is sharp.
• Fixed line vs auto-feed: This head uses fixed line you cut to length manually. It won’t auto-feed like the stock Ryobi head—you’ll stop to advance line by hand.
• Blade performance: The plastic blade is effective for thick weeds but dulls quickly on rocks or hard surfaces. Keep spare blades on hand.
• Common gotcha: The head can loosen during heavy use if not fully tightened. Check snugness after 10–15 minutes of trimming.

Should You Buy It

Buy this if you have a compatible straight-shaft Ryobi trimmer and want a durable, two-in-one head for switching between line and blade work without buying a separate attachment. It’s a solid upgrade for users who tackle mixed terrain, but skip it if you prefer the convenience of auto-feed line or have a curved-shaft model.
