Thten KSLA 58040-03 KAL 580-06 0.080 inch 144ft Trimmer Pre Cut Compatible with Kobalt Gen4 4768425,1438130,5218445,4926600,623439,1130001,820915,1160325,3854567,2857514,4913866,2808608 Trimmer 9 Pack

What It Is

This is a 9-pack of pre-cut 0.080-inch diameter, 144-foot total trimmer line designed for Kobalt Gen4 80V string trimmers. It’s a replacement line for medium-duty trimming of grass and light weeds.

Fitment & Compatibility

Check your trimmer model number against the list: 4768425, 1438130, 5218445, 4926600, 623439, 1130001, 820915, 1160325, 3854567, 2857514, 4913866, 2808608. This line fits Kobalt Gen4 80V trimmers only—not older 40V or gas models. The 0.080-inch diameter is thicker than standard 0.065-inch line, so confirm your trimmer head accepts that size (check the spool or manual). Aftermarket line, not OEM Kobalt, but pre-cut to fit the Gen4 bump-feed head without winding.

Key Things to Know

• Durability: 0.080-inch line is more durable than thinner lines for edges and driveways, but may wear faster on heavy weeds or rocks.
• Installation: Pre-cut pieces drop into the spool—no winding required. But you must insert each piece correctly into the head slots; misalignment causes jams.
• Common Gotcha: Some users report the line breaks more easily than OEM Kobalt line, especially in hot weather or on thick brush. Use for standard grass, not heavy-duty clearing.
• Quantity: 9 pieces total (each about 16 feet) is enough for several refills—good value for the price.

Should You Buy It

Buy this if you own a compatible Kobalt Gen4 80V trimmer and want a budget-friendly, pre-cut line for routine lawn trimming. Skip it if you need heavy-duty performance for thick weeds or prefer OEM reliability for less hassle.
