3️⃣PA6-GF30 REINFORCED NYLON LINE – Upgraded PA6-GF30 glass-fiber reinforced nylon delivers 110 lbs tensile strength versus the 68 lbs of standard copolymer line, extending wear life by 35% in side-by-side abrasion testing. Each 0.065 inch string Trimmer Spool Line is precision-extruded to a tight ±0.002 inch tolerance, so the spool holds its true diameter under high-speed rotation instead of thinning out or snapping at the eyelet.

5️⃣ Package Included: 12x replacement trimmer line spool for Worx trimmer; 2x replacement cap, Every production batch is tested for tensile strength, heat tolerance and UV stability before shipping.
