VIABRICO .105" Weed Eater String, Square Orange Heavy Duty String Trimmer Line, Weed Wacker String Universal Commercial Grade, Premium Nylon Weedeater Line 0.105" x 2.2LB, 330Foot

What It Is

This is a .105-inch square, heavy-duty nylon trimmer line designed for gas-powered string trimmers and weed eaters. It’s built for commercial-grade cutting of thick grass, weeds, and light brush, offering a balance of durability and flexibility.

Fitment & Compatibility

• Line diameter: .105 inch (2.67 mm) – fits trimmers that accept .080–.105 inch line. Check your trimmer’s manual or existing spool for the maximum line diameter; using a thicker line can overload the engine or damage the head.
• Spool type: Universal – works with most bump-feed, fixed-line, and quick-load spools. Not compatible with automatic-feed heads that require specific pre-wound spools.
• Brand/model: No proprietary fit – fits any trimmer with a standard line head (e.g., Echo, Husqvarna, Stihl, Ryobi, Troy-Bilt, Craftsman). Confirm your trimmer’s shaft type (straight vs. curved) only matters for line feeding, not fit.
• Length: 330 feet per 2.2 lb spool – enough for several refills on most home-use trimmers. Weighs 2.2 lbs, so check your trimmer head’s line capacity (typically 15–50 feet per spool).
• OEM vs aftermarket: Aftermarket line; no warranty implications, but verify your trimmer’s line diameter limit to avoid voiding the engine warranty if the line is too thick.

Key Things to Know

• Material: Premium nylon with square profile – cuts cleaner and lasts longer than round line. The square edges act like blades, reducing fraying and breakage on tough weeds.
• Installation: Easy – cut to length, wind onto spool, and feed through eyelets. No special tools required. Watch for overlapping or twisting during winding to avoid jams.
• Performance: Works best on medium to heavy vegetation. Not ideal for very thick brush or woody stems (use .130+ line for that). Expect less vibration than round line.
• Durability: Rated for commercial use – handles frequent contact with fences, rocks, and sidewalks better than standard line. Can be brittle in extreme cold (below 20°F).

Should You Buy It

Yes, if you have a gas trimmer that accepts .105 line and regularly tackle thick grass, brambles, or edges. It’s a solid upgrade over cheap round line for durability and cutting speed. Skip it if your trimmer is electric (line may overload the motor) or if you only need light trimming of manicured lawns.
