YWTESCH 4 Pack CMZST0803 CMZST080 Weed Eater String Trimmer Spool Cap Fit for Craftsman, Weed Eater Head Replacement Part Compatible with Craftsman CMCST910 Series, CMCST910M,CMCST910M1 Weed Wacker

What It Is

This is a 4-pack of replacement spool caps (CMZST0803/CMZST080) for Craftsman and Weed Eater string trimmers. They secure the trimmer line spool inside the head and are designed for electric and gas models that use a bump-feed or fixed-line head.

Fitment & Compatibility

Before buying, confirm your trimmer model. These caps are listed as compatible with Craftsman CMCST910 series (CMCST910M, CMCST910M1) and other Craftsman/Weed Eater trimmers using the CMZST0803 or CMZST080 cap. Check your trimmer’s model number (usually on a sticker near the motor or shaft). Measure the cap diameter—these are roughly 1.5 inches across. They are aftermarket replacements, not OEM Craftsman parts, so fit may vary slightly on older or non-listed models. Avoid if your trimmer uses a different cap design (e.g., push-button or twist-lock).

Key Things to Know

• Quality: Made of plastic; fine for light-to-moderate use. Some users report they fit snugly, but a few note they feel slightly less durable than OEM caps.
• Installation: Easy—remove old cap, align tabs, and snap into place. No tools required. Takes under 2 minutes per cap.
• Gotcha: Ensure the cap’s spring or retaining tabs match your spool. If your trimmer uses a specific spool orientation, test fit before reassembling the whole head.
• Pack value: 4 caps for $7.99 means you have spares, useful if caps crack or get lost during line changes.

Should You Buy It

If you own a compatible Craftsman or Weed Eater trimmer and need a quick, affordable fix for a lost or cracked spool cap, this 4-pack is a solid buy. It’s not for heavy-duty commercial use, but for home lawn care, it’s a cheap way to keep your trimmer running without hunting for OEM parts.
