Ryobi P2002 P2000 18V String Trimmer (2 Pack) Replacement Spool Cap # 522994001-2pk

What It Is

This is a replacement spool cap (part #522994001-2pk) for Ryobi 18V ONE+ string trimmers, specifically the P2000 and P2002 models. It holds the trimmer line spool in place and provides the cutting head’s bump-feed mechanism.

Fitment & Compatibility

Check your model number – this cap fits Ryobi 18V cordless trimmers with part numbers P2000 and P2002 only. It will not fit Ryobi 40V, gas-powered, or older 18V models (e.g., P2001, P2003).
Measure the cap diameter – the OEM cap is ~1.5 inches wide. If your current cap is larger or smaller, this won’t work.
OEM vs aftermarket – this is an official Ryobi replacement, not a third-party knockoff, so fitment is guaranteed for the listed models.
Avoid mix-ups – the cap is sold as a 2-pack; each cap is identical and interchangeable with either P2000 or P2002.

Key Things to Know

• Quality – OEM plastic is durable but can crack if overtightened or dropped repeatedly. The 2-pack gives you a backup.
• Installation – tool-free snap-on/off design. Takes 30 seconds: remove old cap, align tabs, press until it clicks. No screws or special tools.
• Common gotcha – the cap can be hard to remove if line is jammed. Use a flathead screwdriver to gently pry it off (don’t force it).
• Compatibility trap – some aftermarket spools have slightly different tab alignment; this OEM cap only works with Ryobi-branded spools.

Should You Buy It

If you own a Ryobi P2000 or P2002 trimmer and your current cap is cracked, worn, or lost, this 2-pack is a cheap, reliable fix. It’s also smart to keep one as a spare if you trim frequently. Skip it if you have a different Ryobi model (40V or gas) or want a cap that fits aftermarket spools.
