105 Trimmer Line, Weed Eater String 105, Weed Wacker String 105, String Trimmer Line .105, Round Weed Eater Line .105 Inch-1038Ft-5Lb, Heavy Duty Weed Wacker Line 105 Fits Most String Trimmers(Round)

What It Is

This is a 0.105-inch diameter round trimmer line, sold in a 5-pound bulk spool (1,038 feet total). It’s designed for heavy-duty trimming of thick grass, weeds, and light brush, and fits most standard string trimmers that accept round line.

Fitment & Compatibility

Before buying, confirm your trimmer’s line diameter range (check the manual or existing line). This .105-inch line works with most gas and electric trimmers that accept .095 to .110-inch line, but not all. Specifically:

• Bump-feed heads usually work, but check the head’s line capacity (some hold only shorter lengths).
• Fixed-line heads may need trimming to fit.
• OEM vs aftermarket: This is a universal aftermarket line. No brand-specific fit issues, but avoid it if your trimmer requires square or serrated line (this is round only).
• Measurement: .105 inch = 2.67 mm. If your trimmer says “2.4 mm” or “3.0 mm” max, this may jam or break the head.

Key Things to Know

• Quality: Round line is less durable than square or star-shaped line—expect faster wear in rocky or abrasive conditions.
• Installation: Easy to wind onto spools, but the bulk spool requires manual cutting (no pre-cut lengths). Use a sharp blade to avoid fraying.
• Common gotcha: Overfilling the spool causes line jams. Stick to the head’s capacity (usually 15-25 feet per side).
• Performance: Cuts well on grass and weeds, but struggles with thick woody brush. For heavy-duty jobs, consider a .095 or .130 line.

Should You Buy It

Buy this if you need a large, cost-effective supply of standard round line for regular lawn maintenance on a trimmer that accepts .105-inch line. Skip it if you trim dense brush or have a trimmer with a narrow line channel (under .095-inch).
