Arnold Professional Grade String Trimmer Line - .105-Inch x 90-Foot - Universal Fit, (WLX-H105)

What It Is

This is a .105-inch diameter, 90-foot spool of round trimmer line designed for gas, electric, and battery-powered string trimmers. It’s a universal-fit aftermarket replacement for general residential and light commercial trimming of grass and weeds.

Fitment & Compatibility

• Diameter: .105-inch (2.7mm) – fits trimmers that accept line from .080 to .110-inch. Check your trimmer’s manual or head for the max line diameter; using a larger size can overload the engine or damage the head.
• Length: 90 feet – enough for multiple refills or a single full spool on most standard trimmers.
• Brand/model: Universal fit, but not compatible with trimmer heads that require pre-cut line pieces (e.g., some bump-feed or fixed-line heads). Works best with standard spool-loading heads.
• OEM vs aftermarket: This is an aftermarket line. It’s not a direct OEM replacement for any specific brand (e.g., Echo, Stihl, Husqvarna), but the .105-inch round profile fits most common heads.

Key Things to Know

• Round line only: This is a basic round line, not twisted or serrated. It’s fine for light grass but will wear faster on thick weeds or against hard surfaces like sidewalks.
• Installation: Easy – just wind onto the spool. No special tools needed, but avoid overlapping or jamming the line in the head.
• Durability: Arnold Professional Grade is decent for the price, but it’s not heavy-duty. Expect to replace more often than premium brands (e.g., Oregon, Stihl) if you cut tough brush.
• Gotcha: The spool has a small center hole; make sure your trimmer head’s spool retainer fits snugly. Some aftermarket spools may wobble on certain heads.

Should You Buy It

Buy this if you need a budget-friendly, universal .105-inch line for regular lawn trimming and don’t mind replacing it more often than premium options. It’s a solid value for homeowners with standard electric or gas trimmers. Skip it if you need a heavy-duty line for thick weeds or commercial use.
