KAKO 105 Trimmer Line, Weed Eater String .105, Weed Wacker String .105, Round Weed Trimmer Line .105Inch-1038Ft-5Lb, Weed Wacker Line .105 Fits Most String Trimmers

What It Is

The KAKO 105 is a 0.105-inch diameter round trimmer line, sold in a 5-pound spool (1,038 feet total). It’s designed for gas and electric string trimmers that accept a medium-duty line, suitable for clearing grass, weeds, and light brush around lawns, gardens, and fence lines.

Fitment & Compatibility

• Line diameter: 0.105 inches (2.67 mm). This fits most trimmers that specify 0.095–0.105 inch line. Check your trimmer’s manual or the existing line spool for the max diameter rating—using too thick a line can overload the engine or damage the head.
• Trimmer type: Works with both bump-feed and fixed-line heads, but not for automatic-feed heads (those require pre-cut, not bulk spool line). If you have a SpeedFeed or similar head, confirm it accepts bulk line.
• Brand/Model: No specific brand lock-in; fits most major brands (Echo, Husqvarna, Stihl, Ryobi, etc.) as long as head compatibility is verified.
• OEM vs aftermarket: This is aftermarket. It’s a direct replacement for OEM line of the same diameter, but some OEM heads (e.g., Stihl AutoCut) may require a specific line shape (e.g., star or square) for optimal feeding—round line can slip in those heads.

Key Things to Know

• Line quality: Round profile is universal but less aggressive than twisted or square line. It’s fine for grass and light weeds, but will wear faster on heavy brush or rocks. The 5-pound spool is economical for frequent users.
• Installation: Easy—just cut to length and wind onto your spool. No special tools needed. If your head uses pre-cut pieces, you’ll need to cut 8–12 inch lengths yourself.
• Common gotcha: Round line can fuse in the head if you overload it or use in high heat. Avoid over-winding (leave 1/4 inch gap on the spool). Also, if your trimmer requires a specific line shape for auto-feed, this round line may cause jamming.
• Durability: KAKO’s line is UV-resistant and holds up well in sun, but it’s not reinforced—expect to replace it more often than premium twisted lines in heavy use.

Should You Buy It

Buy this if you have a standard gas or electric trimmer that accepts 0.105-inch round line, and you want a large, cost-effective supply for routine grass and weed trimming. Skip it if your trimmer head requires shaped line (star, square, or serrated) for reliable feeding, or if you regularly cut dense brush where a heavier-duty line would last longer.
