KAKO 0.105 in Square Trimmer Line — 628 ft (3 lb) Commercial Nylon, Heavy-Duty Cut & Low Vibration

Engineered for professional and homeowner string trimmers, this square .105 trimmer line combines a high-toughness inner core with abrasion-resistant nylon to deliver longer life and stronger cutting performance than many round or twisted alternatives. The KAKO 105 fits most popular brands and spools, giving you a reliable refill that reduces breakage, vibration and engine strain while making yard cleanup faster.

How does the square shape improve cutting compared to round line?

The square profile presents sharper edges to the vegetation, producing cleaner cuts and increased impact per rotation. That shape displaces less air than bulkier profiles while maintaining rigidity, so it slices through dense weeds with fewer passes and less engine effort.

• Sharper cutting edges for more effective slicing
• Lower air drag than thicker round profiles
• Fewer line passes to clear the same area
• Reduced engine torque demand and vibration

Will this KAKO .105 trimmer line work with my trimmer model?

Yes — the 0.105 inch (2.7 mm) diameter is compatible with a wide range of string trimmers and automatic bump feed spools. It is suitable for brands such as Echo, Husqvarna, Ryobi, Redmax, Black & Decker, Cub Cadet, Weed Eater and many aftermarket spools that accept .105-inch lines.

• Diameter: 0.105 inch (2.7 mm) — standard fit for many spools
• Length: 628 feet — enough for multiple refills or heavy use
• Weight: 3 lb spool — commercial quantity for pro users
• Square profile — compatible as long as the spool accepts square or similar-shaped line

How durable is the KAKO 105 line and what can I expect in daily use?

The line uses quality nylon with a reinforced inner core to resist snapping and wear, designed for extended service in demanding conditions. You can expect fewer breaks when trimming around rocks, roots and debris compared with weaker or twisted lines, which means less downtime reloading.

• High-toughness core to resist breakage
• Abrasion-resistant outer nylon for longer life
• Performs well on heavy weeds and thick grass
• Less frequent spool changes during long jobs

How much line is included and how should I store it?

Each spool supplies 628 feet of .105-inch square trimmer line, packaged as a single 3-pound coil suitable for commercial and home use. Store the line in a cool, dry place away from direct sunlight and chemicals to prevent softening or brittleness; keeping it on the original spool helps prevent tangles and simplifies installation.

• 628 feet per spool — multiple refills possible
• 3 lb weight — commercial quantity for extended jobs
• Store in cool, dry, shaded area away from solvents
• Keep on spool to avoid kinks and easy loading

Who is this for? KAKO's .105 square trimmer line is aimed at landscapers, rental operations, and homeowners who need a durable, efficient line for frequent or heavy-duty trimming. If you regularly cut dense grass, invasive weeds, or maintain acreage where line durability and cutting power matter, this commercial-grade spool gives more runtime and fewer reloads than standard consumer options.
