MaxPower 338933 0.105-in. x 550-ft. CAT6® Twisted Trimmer Line

What It Is

The MaxPower 338933 is a 0.105-inch diameter, 550-foot spool of CAT6® twisted trimmer line designed for gas, electric, and battery-powered string trimmers. It’s built for light to medium-duty trimming of grass and small weeds.

Fitment & Compatibility

Before buying, check your trimmer’s line diameter requirement—0.105-inch fits most standard consumer trimmers (e.g., Echo, Husqvarna, Ryobi, Craftsman), but some models require 0.095 or 0.130. Measure your spool capacity: 550 feet is a bulk spool meant for refilling multiple times, not a single pre-wound spool. Verify your trimmer uses a single-line or bump-feed system (not a fixed-line head). This is an aftermarket part; no OEM cross-reference needed.

Key Things to Know

• Twisted design reduces noise and vibration compared to round line, but it’s less aggressive than serrated or square line for thick weeds.
• Installation is straightforward if you follow the spool’s winding direction—most trimmers wind clockwise, but check your manual to avoid jamming.
• 0.105-inch is a “tweener” size—too thin for heavy brush, too thick for lightweight grass. It balances cut quality and runtime.
• Spool is bulk, not pre-cut—you’ll need to cut your own lengths (typically 12-15 feet per refill). Keep scissors handy.

Should You Buy It

Buy this if you want a quiet, smooth-running line for routine lawn maintenance on a standard trimmer and prefer buying in bulk to save per-foot cost. Skip it if you need heavy-duty line for thick weeds or brambles, or if your trimmer requires a specific diameter like 0.095 or 0.130.
