String Trimmer Line, Commercial Grade Orange Pentagon Weed Eater String, Premium Nylon Universal 0.080" Diameter x 1LB, by 525 Foot

What It Is

This is a 0.080-inch diameter commercial-grade trimmer line made from premium nylon in a pentagon (5-sided) shape. It’s designed for heavy-duty trimming on gas trimmers, clearing thick grass, weeds, and light brush.

Fitment & Compatibility

• Diameter: 0.080" – fits most trimmer heads that accept line sizes from 0.065" to 0.095". Check your trimmer’s manual or head for max line diameter.
• Brand/Model: Universal fit – works with any brand (Stihl, Echo, Husqvarna, Ryobi, etc.) as long as the head supports a single 0.080" line.
• Length: 525 feet per 1 lb spool – enough for many refills. No need to match OEM line; this is aftermarket but compatible.
• What to check: Measure your current line diameter with calipers. Confirm your trimmer head is a “bump-feed” or “manual-feed” type (not a pre-cut blade system). Avoid if your head requires 0.095" or larger line.

Key Things to Know

• Durability: Pentagon shape cuts through thick weeds faster than round line and lasts longer due to more edge contact. Good for rocky areas.
• Installation: Easy to load – unwind and thread through head. No special tools needed. May require cutting to length for manual-feed heads.
• Common gotcha: 0.080" is thinner than heavy-duty line (0.095"+), so it may snap faster on dense brush. Not ideal for brush cutters or clearing heavy saplings.
• Noise/feed: Runs quieter than twisted lines. Bump-feed works reliably, but avoid over-tightening the spool.

Should You Buy It

Buy this if you have a standard gas trimmer and regularly tackle thick weeds, briars, or overgrown grass. It’s a solid upgrade from cheap round line for the price, but skip it if you need heavy-duty 0.095"+ line for brush cutting or if your head specifically requires a larger diameter.
