A ANLEOLIFE 3-Pound Heavy Duty Octa-Twist .155-Inch-by-379-ft Trimmer Line Spool,OTRIXT Co-Extruded Multi-Edge Spiral Weed Eater String, Red

What It Is

A pre-wound replacement spool for gas and electric string trimmers, designed for heavy-duty cutting of thick weeds and brush. The octa-twist, multi-edge co-extruded design (0.155-inch diameter, 379 feet total) delivers aggressive cutting performance with reduced line breakage.

Fitment & Compatibility

• Line diameter: 0.155-inch – fits most standard trimmer heads that accept .155 or .160 line. Do not use in heads requiring .130 or smaller line.
• Spool dimensions: Check your trimmer’s spool well diameter and depth. This spool is designed for universal fit, but some proprietary brands (e.g., Echo Speed-Feed, Husqvarna T35) may require their own spool. Measure your existing spool’s center hole size and overall width.
• OEM vs aftermarket: This is an aftermarket spool. It may not engage the bump-feed mechanism correctly on certain brand-specific heads. Test-fit before winding.
• What to measure: Spool width (typically 1.5–2.2 inches), center hole diameter (usually 0.5–0.75 inches), and overall spool height.

Key Things to Do

• Confirm bump-feed compatibility: Some trimmer heads require a specific spool design for reliable line advancement. If your head has a metal pin or spring-loaded catch, this spool may not lock in properly.
• Installation difficulty: Easy – remove old spool, drop in new one, thread line through exit eyelet. No winding required. However, the stiff line may resist initial feeding; gently bend the tip to start.
• Line quality: Co-extruded construction (nylon outer, polymer core) resists heat and abrasion better than standard round line. The octagonal edges cut through brambles and poison ivy effectively but can wear faster on pavement.
• Gotcha: The 379-foot length is split across two spool halves (189.5 ft each). If your trimmer uses a single large spool, you may need to split the line yourself.

Should You Buy It

Buy this if you have a universal-fit trimmer head (most Ryobi, Craftsman, Greenworks, or Black+Decker models) and regularly tackle thick weeds, blackberries, or saplings. Skip it if you own a trimmer with a proprietary bump-feed head (Echo, Husqvarna, Stihl) unless you confirm compatibility first. The price is fair for the heavy-duty performance, but check your spool well dimensions before ordering.
