Cluparis .105-Inch Heavy Duty Trimmer Line, 5lb 1076ft Professional Square Weed Eater String, 3-Component Tri-Extrusion for Extra Durability, Fits Echo Husqvarna Ryobi, with Super Line Cutter

What It Is

This is a .105-inch diameter, 5-pound spool of heavy-duty trimmer line (1,076 feet total) designed for gas and electric string trimmers. The tri-extrusion construction and square profile boost cutting durability for thick weeds and brush, and it includes a Super Line Cutter tool for quick replacement.

Fitment & Compatibility

Before buying, verify your trimmer accepts .105-inch line (common on Echo, Husqvarna, Ryobi, and other mid-to-large trimmers). Check your trimmer’s manual for max line diameter—.105 is too thick for most light-duty electric trimmers (e.g., 18V Ryobi or small 2-cycle models). The spool is universal (fits any trimmer head that loads bulk line), not a specific brand’s pre-wound spool. No deck size or OEM part number applies; this is purely aftermarket.

Key Things to Know

• Durability: The tri-extrusion (3-layer) design resists breaking on rocks and fences better than standard round line, but it’s not indestructible—expect occasional fraying on heavy abuse.
• Installation: Manual winding required; the included Super Line Cutter helps cut cleanly, but winding a 5-lb spool can be tedious if you don’t have a line winder or drill attachment.
• Compatibility gotcha: Some trimmer heads have narrow line slots—measure before buying. .105 may not feed smoothly in heads designed for .080 or .095 line.
• Storage: 5 lbs is bulky; store in a dry place to prevent moisture damage to the line over time.

Should You Buy It

Buy this if you have a mid-to-large gas trimmer (Echo, Husqvarna, Ryobi 40V/80V) and cut heavy grass or brush frequently—the bulk spool saves money vs. small packs. Skip it for light-duty electric trimmers or if you prefer pre-wound spools for quick changes.
