Eventronic 8 Pack CMZST0803 CMZST080 Weed Eater String Compatible with Craftsman Weed Wacker, 0.080" 20Ft String Trimmer Line, Auto Feed Weed String Line Fit for Craftsman CMCST910 Series

What It Is

This is an 8-pack of 0.080-inch diameter, 20-foot pre-wound trimmer line spools designed specifically for Craftsman weed wackers. The line is pre-loaded onto auto-feed spools, so you can swap spools without manually winding line or fighting with bump-head mechanisms.

Fitment & Compatibility

• Trimmer line diameter: 0.080 inches (must match your trimmer head’s line size—check your manual or existing spool)
• Compatible models: Craftsman CMCST910 series (e.g., CMCST910, CMCST910F2) and many other Craftsman weed wackers that use the CMZST080/CMZST0803 spool design
• OEM vs aftermarket: This is a direct replacement for Craftsman part numbers 753-04869, 753-04870, and 753-04871. Not a universal fit—verify your trimmer uses the same spool form factor
• What to check before buying: Measure your existing spool’s diameter and line thickness. If your trimmer uses a different line gauge (e.g., 0.065 or 0.095), this pack won’t work

Key Things to Know

• Installation difficulty: Very easy—pop off the old spool, snap in the new one, thread the line through the eyelets. No winding required
• Line quality: The 0.080 line is medium-duty—good for light to moderate trimming (grass, weeds, small brush). Not designed for heavy-duty clearing or thick woody growth
• Common gotcha: Auto-feed heads can jam if the line is too long or if you overfill the spool. Trim the line to the manufacturer’s recommended length (usually 6-8 inches exposed) after installation
• Pack value: 8 spools at $9.99 works out to ~$1.25 per spool—cheaper than buying single OEM spools, but line may wear faster than premium aftermarket brands

Should You Buy It

Buy this if you own a Craftsman CMCST910-series trimmer or another model that uses the CMZST080 spool and want a convenient, no-wind replacement that saves time during mowing season. Skip it if you need a heavier line for thick brush or if your trimmer uses a different spool shape or line diameter.
