0.080'' DWO1DT802 Replacement String Timmer Lines Compatible with DEWALT Weed Eater, Square Twisted Weed Eater String, Heavy Duty Trimmer String (240 ft.)

What It Is

This is a 0.080-inch diameter, square-twisted replacement trimmer line designed for DEWALT cordless and gas weed eaters, ideal for heavy-duty trimming of dense grass, weeds, and light brush.

Fitment & Compatibility

• Line diameter: 0.080’’ – fits any trimmer head that accepts this size (common on DEWALT 20V/60V cordless models like DWO1DT802, DCMW220, and DCMW240).
• Line shape: Square-twisted – improves cutting efficiency and durability over round line, but requires a trimmer head that can handle twisted line (most bump-feed and fixed-line heads work).
• Compatibility: Aftermarket, not OEM DEWALT. Works with many brands (Ryobi, Echo, Husqvarna) if head accepts 0.080’’ line, but check your trimmer’s manual for max line diameter.
• What to check: Measure your current line diameter with a caliper or match the spool’s labeled size. Verify your trimmer head’s line capacity (length per spool) – 240 ft. is a bulk spool, not a pre-wound spool.

Key Things to Know

• Installation: You must manually wind this onto an empty spool. Not difficult, but take care to wind tightly and evenly to avoid tangling.
• Durability: Square-twisted design lasts longer than round line in heavy weeds, but can be noisier and may wear down trimmer head edges over time.
• Breakage: 0.080’’ is thicker than standard 0.065’’ line – it’s tougher but may snap if you hit hard objects (rocks, fences) at full speed. Reduce RPM if needed.
• Storage: Keep in a cool, dry place. Moisture can cause the line to become brittle or stick together on the spool.

Should You Buy It

If you have a DEWALT trimmer that takes 0.080’’ line and need a heavy-duty option for thick weeds or overgrown areas, this is a solid, cost-effective choice. Skip it if you prefer pre-wound spools or if your trimmer head only accepts thinner line (0.065’’ or less).
