String Weed Trimmer Line Replacement for DEWALT DWO1DT802, 0.080 Inch 50-Feet - Compatible with DCST922P1 DCST925 DCST925B DCST972 DCST972B DCST925M1 DCST920B DCST970B

What It Is

This is a 0.080-inch diameter, 50-foot spool of replacement string trimmer line designed for DEWALT cordless string trimmers. It’s a standard round trimmer line for light to medium trimming tasks like edging along sidewalks, fences, and flower beds.

Fitment & Compatibility

Check these before buying:

• Model compatibility: Fits DEWALT models DCST922P1, DCST925, DCST925B, DCST972, DCST972B, DCST925M1, DCST920B, and DCST970B. It’s the OEM replacement for DWO1DT802.
• Line diameter: 0.080 inch (2.0 mm). Confirm your trimmer’s head accepts this thickness. Thicker line may not feed properly or could overload the motor.
• Spool vs. bulk line: This is a pre-wound spool, not a bulk spool. If your trimmer uses a different spool design (e.g., bump-feed or fixed-line), you may need to re-spool.
• OEM vs. aftermarket: This is genuine DEWALT line, so fitment and feed reliability are guaranteed. Aftermarket alternatives may vary in stiffness or durability.

Key Things to Know

• Durability: Standard round line – good for grass and light weeds, but will wear faster on thick brush or against concrete. Not for heavy-duty clearing.
• Installation: Easy if you follow the spool winding direction (usually clockwise). Miswinding causes jamming or poor feeding.
• Length: 50 feet is enough for 3–5 full refills on most DEWALT trimmers, depending on usage.
• Common gotcha: Ensure the trimmer head is clean and free of debris before installing. Old line fragments can cause feed issues.

Should You Buy It

Buy this if you need a direct OEM replacement for your compatible DEWALT trimmer and want reliable, hassle-free feeding for routine yard trimming. Skip it if you need thicker (.095” or .105”) line for heavy brush, or if you prefer bulk spools to save money.
