Husqvarna Titanium XPro Trimmer Line — 0.105in.Dia. x 690ft.L, 3-Lb. Spool

What It Is

This is a 3-lb. spool of Husqvarna Titanium XPro trimmer line, 0.105 inches in diameter and 690 feet long. It’s designed for heavy-duty trimming in commercial or large residential use, compatible with most gas and battery-powered string trimmers that accept .105-inch line.

Fitment & Compatibility

Before buying, check your trimmer’s line diameter specs—this is 0.105 in., not the common .080 or .095. It fits trimmers with a standard bump-feed or fixed-line head that can handle a 3-lb. spool. Husqvarna models like the 525L, 545RX, and 555RXT are direct fits, but it also works with many other brands (e.g., Stihl, Echo, Ryobi) if the head accepts .105 line. Measure your existing spool’s diameter and arbor hole—this spool is 8.5 inches wide and uses a 1-inch center hole. For aftermarket heads, confirm compatibility with the spool’s internal locking mechanism (usually a spring-loaded pawl). OEM vs. aftermarket: this is genuine Husqvarna, so it guarantees fit on Husqvarna heads but may require an adapter for others.

Key Things to Know

• Quality: Titanium-infused line resists fraying and breakage better than standard nylon, lasting 2-3x longer in abrasive conditions (e.g., rocky or fence-line trimming).
• Installation: Easy to install on Husqvarna heads—just snap the spool in and thread the line. On non-Husqvarna heads, you may need to cut the line to length and manually wind it, which takes extra time.
• Gotcha: The .105 diameter is thicker than most homeowner lines, so it’s heavier and can reduce RPM on smaller trimmers (under 25cc). Not ideal for light-duty or electric trimmers unless the manual specifies .105.
• Spool size: 690 ft. is a lot of line—great for pros or large properties, but overkill for a single yard. Store in a cool, dry place to prevent brittleness.

Should You Buy It

Buy this if you run a commercial or heavy-use trimmer (25cc+) and need a durable line that lasts through thick weeds, briars, or roadside trimming. Skip it if you have a small electric trimmer or only edge a lawn—the thicker line will bog down your machine and waste money.
