Husqvarna 529337611 Titanium XPro Round Trimmer Line 115' 1/2lb Spool .105"

What It Is

The Husqvarna 529337611 is a pre-wound spool of .105-inch (2.7mm) Titanium XPro round trimmer line, delivering 115 feet of line per 1/2-pound spool. Designed for heavy-duty trimming in commercial or residential use, it’s built to cut through thick grass, weeds, and light brush without frequent line breakage.

Fitment & Compatibility

• Trimmer Head Type: Fits most Husqvarna trimmers with a Speed-Feed or T35-style bump-feed head. Also compatible with some Craftsman, Poulan, and McCulloch models using the same head design.
• Line Diameter: .105-inch (2.7mm) – check your trimmer’s manual for max line diameter; larger heads may accept .105”, but some consumer models cap at .095”.
• Spool Size: 1/2-pound spool (115 ft). Verify your trimmer head can hold a spool of this width (typically about 1.5 inches tall). Not compatible with mini or compact heads.
• OEM vs Aftermarket: This is a genuine Husqvarna part – directly interchangeable with OEM spools for Husqvarna, but may not fit generic aftermarket heads without modification.

Before buying: Measure your current spool’s width and confirm your trimmer model number (e.g., 128LD, 324L, 525LST) supports .105” line. If your head uses pre-cut line lengths rather than a spool, this won’t work.

Key Things to Know

• Quality: Titanium XPro uses a titanium-infused polymer that resists fraying and snapping better than standard nylon line. Lasts 30–50% longer in abrasive conditions (sidewalks, rocks).
• Installation: Bump-feed spools are drop-in replacements – no winding required. Just remove the old spool, insert the new one, and thread the line through the eyelets.
• Common Gotchas: The .105” diameter is too thick for many residential trimmers (e.g., 125B, 130BT). Using oversized line can overload the engine or damage the head. Always confirm your trimmer’s max line size.
• Noise/Vibration: Slightly louder than thinner lines due to heavier cutting action, but vibration is minimal with the round profile.

Should You Buy It

This spool is ideal for commercial landscapers or homeowners with heavy-duty Husqvarna trimmers who need to clear thick weeds and brush without constant line replacement. If your trimmer accepts .105” line and you value durability over low cost, it’s a strong upgrade from standard nylon. Skip it if you have a light-duty electric or gas trimmer that caps at .095” or smaller line.
