Oregon 22-205 Magnum Gatorline Round Trimmer Line .105-Inch by 114-Foot

What It Is

The Oregon 22-205 Magnum Gatorline is a .105-inch round trimmer line designed for heavy-duty trimming in gas and electric string trimmers. It’s a 114-foot spool intended for commercial users or homeowners with thick weeds, overgrowth, or rocky terrain.

Fitment & Compatibility

• Line diameter: .105 inches (2.7 mm) – fits most standard trimmer heads accepting .080–.105-inch line. Check your trimmer’s manual for max line size; oversized line can jam or overload the motor.
• Spool type: Universal replacement spool – works with bump-feed, fixed, or manual-feed heads. Not compatible with EGO’s proprietary “Powerload” heads (those require specific EGO spools).
• Brand compatibility: Oregon brand aftermarket – fits many trimmers (EGO, Stihl, Husqvarna, Echo, etc.), but verify your head’s line-retention system (e.g., notched or hole-based). For EGO Powerload heads, you’ll need to manually wind this line onto an EGO spool.
• Measurements: Spool width ~2.5 inches, hub diameter ~1.5 inches – fits most standard trimmer heads. Check your head’s internal clearance for a snug fit.

Key Things to Know

• Cutting performance: Round shape with “Gatorline” serrated edges grips and slices through heavy grass, brambles, and saplings better than smooth round line. Less breakage than standard round line.
• Installation: Moderate difficulty – spool is pre-wound, but you may need to thread through your head’s eyelets. For EGO Powerload heads, you must manually rewind onto an EGO spool (no quick-load compatibility).
• Durability: .105-inch thickness reduces wear against concrete and rocks, but can be overkill for light trimming (may bog down smaller electric trimmers).
• Common gotcha: Spool unwind tension can be tight – if your head uses a spring-loaded mechanism, ensure the line feeds freely after loading to avoid jamming.

Should You Buy It

Yes, if you have a heavy-duty trimmer (gas or high-voltage electric) and need serious line for thick weeds, brush, or roadside trimming. Skip if you have a small electric trimmer or a proprietary EGO Powerload head – you’ll need to manually rewind, which is tedious.
