Oregon 19-005 Gatorline Square String Trimmer Line Precut .155-Inch Diameter x 18-Inch Length 24-Piece Tube

What It Is

This is a precut, .155-inch diameter square string trimmer line designed for heavy-duty trimming of thick grass, weeds, and light brush. It’s intended for use with EGO string trimmers and other brands that accept .155-inch line, typically in commercial or residential gas and cordless models.

Fitment & Compatibility

Before buying, confirm your trimmer’s line diameter requirement—most EGO models (e.g., Power+ series) use .095 or .080-inch line; .155-inch is thicker and may not fit. Check your trimmer’s manual or head for the maximum line diameter. This line is 18 inches long per piece, so ensure your trimmer head can accommodate that length. It’s aftermarket, not OEM, but widely compatible with brands like EGO, Stihl, Husqvarna, and Ryobi as long as diameter matches. Measure your existing line’s thickness with calipers to avoid jams.

Key Things to Know

• Durability: Square shape provides more cutting surface than round line, reducing wear and improving edge-on-weed contact. The Gatorline formula includes nylon with aramid fibers for added strength.
• Installation: Precut 18-inch lengths save time—no winding spools. However, some trimmer heads require specific line lengths; measure before cutting further.
• Common gotcha: .155-inch is heavy-duty; it may overload smaller electric trimmers (under 15-amp) or cause overheat. Use only if your trimmer is rated for this gauge.
• Noise/vibration: Thicker line can increase vibration and noise on some heads, especially if not balanced properly.

Should You Buy It

Buy this if you have a high-powered gas or cordless trimmer (e.g., EGO 56V, Stihl FS 90+) and need to cut dense weeds or brambles without frequent line breakage. Skip it for light residential trimming or if your trimmer’s max line diameter is smaller than .155-inch.
