.105" String Trimmer Line, Commercial Grade Orange Pentagon Weed Eater String, Premium Nylon Universal 0.105" Diameter x 328'

What It Is

This is a 0.105" diameter, 328-foot spool of commercial-grade pentagon-shaped nylon string trimmer line. Designed for heavy-duty trimming and edging on gas, electric, and battery-powered string trimmers that accept 0.105" line.

Fitment & Compatibility

Check your trimmer’s owner manual for the maximum line diameter it can accept. Most standard residential trimmers use 0.080"–0.095" line; 0.105" is thicker and fits commercial or high-output trimmers (e.g., Echo SRM-225, Stihl FS 91, Husqvarna 128LD). Confirm your trimmer’s bump head or fixed head can spool 0.105" line—some heads have a smaller exit eyelet that will jam. Measure your current line with a caliper or ruler (0.105" ≈ 2.67 mm). Universal fit, but not recommended for lightweight electric trimmers with 0.065"–0.080" max capacity.

Key Things to Know

• Commercial-grade durability: Pentagon shape cuts through thick weeds and brush better than round line, but wears faster on pavement or concrete edges.
• Installation is standard: Spool or cut to length (typically 15–20 feet per reload). No special tools needed, but pre-cutting the line at an angle helps feed into bump heads.
• Common gotcha: Using 0.105" in a trimmer rated for 0.095" max can overload the motor, cause frequent line breakage, or damage the head. Always verify max diameter.
• Price per foot: At ~$0.04/ft, this is cheaper than most hardware-store spools, but you get a full 328’—great for frequent users.

Should You Buy It

Buy this if you have a mid-to-high-end gas or battery trimmer that accepts 0.105" line and you need a large, affordable spool for heavy-duty clearing of overgrown grass, briars, or brush. Skip it if your trimmer is a lightweight electric model or you only edge a small lawn—the thicker line will be overkill and may cause issues.
