What It Is

This 4-pack includes replacement spool caps and springs for BLACK+DECKER string trimmers, designed to secure the trimmer line spool in place and provide tension for automatic line feed. It’s for users needing to replace worn or lost caps on compatible models.

Fitment & Compatibility

• Check your trimmer model: This kit is specifically for BLACK+DECKER AFS (Automatic Feed System) trimmers, including the RC100P, GH900, GH1000, LST136, and similar AFS models. Not for non-AFS or other brands.
• OEM vs aftermarket: These are aftermarket parts, not genuine BLACK+DECKER. They match OEM part numbers 90573352 and 90573353 but may have slight fit differences.
• Measure before buying: The cap diameter is approximately 1.5 inches. Ensure your spool housing accepts this size. The spring length is about 1.2 inches; verify it matches your original spring’s coil count (typically 6-8 coils).
• Verify spool type: Works with .065” to .080” line spools that use a center cap retention system. Not for bump-feed or fixed-line heads.

Key Things to Know

• Quality: Caps are plastic; they hold up well for light to medium use but may crack under heavy abuse or if overtightened.
• Installation difficulty: Easy – remove old cap, insert spring into housing, place cap over spool, and snap into place. No tools needed.
• Common gotcha: The spring must sit centered in the housing, or the cap won’t lock. If the cap spins freely, the spring is misaligned.
• 4-pack value: You get four caps and four springs, useful for multiple trimmers or as backups. One cap fits one trimmer.

Should You Buy It

This is a good buy if you own a BLACK+DECKER AFS trimmer and need a cheap, quick fix for a lost or broken spool cap. It’s not for heavy-duty commercial use or non-AFS models. If you prefer exact OEM fit, buy genuine BLACK+DECKER parts instead. For casual homeowners, this 4-pack saves money and hassle.
