105 Weed Eater String, 120-feet Pentagram Shape Heavy Duty String, for Electric & Gas Weed Wacker Using Trimmer Line .105，Used for Stubborn Weed Cleanup, Lawn Repair and Edge Trimming

What It Is

This is a 120-foot spool of .105-inch pentagon-shaped trimmer line designed for electric and gas weed wackers. It’s intended for heavy-duty cleanup of stubborn weeds, lawn edging, and repair work.

Fitment & Compatibility

Before buying, check your trimmer’s line diameter spec—this is .105 inch, which fits most standard string trimmers but may not work with models requiring .080, .095, or .130 line. Measure your existing line or consult your owner’s manual. It’s an aftermarket line, not OEM, so it will fit any trimmer that accepts .105 line, but you may need to adjust cutting head tension or replace the spool. Not compatible with auto-feed heads that require a specific brand or shape.

Key Things to Know

• Quality: Pentagonal shape cuts through thick weeds and grass more aggressively than round line, but it may wear faster on abrasive surfaces like concrete or gravel.
• Installation: Easy to spool by hand—no special tools. Use the winding direction marked on your trimmer head to avoid tangling.
• Common gotchas: .105 line is thicker than standard .080, so it may cause vibration or overload on low-power electric trimmers. Check your trimmer’s maximum line size before use.
• Length: 120 feet is generous—enough for multiple refills on most trimmer heads.

Should You Buy It

Buy this if you have a gas or high-powered electric trimmer that accepts .105 line and you regularly battle tough, overgrown weeds. It’s a solid value for heavy-duty trimming, but skip it if you have a lightweight electric trimmer or need a thinner line for light grass and edging.
