Professional Square Trimmer Line Ø 2.4 mm x 15 m Fluo Yellow on Hanging Card - Part Number: 600474

The professional square string trimmer line (part number 600474) is an aggressive, high-efficiency cutting monofilament engineered for medium-displacement petrol brushcutters, cordless battery systems, and electric grass trimmers. Formulated from premium high-density polyamide polymers, it features a nominal 2.4 mm diameter with a distinct four-corner square profile and an overall length of 15 meters, presented on a practical retail hanging card. The square cross-section acts like razor-sharp shearing edges against vegetation, delivering clean and decisive cuts through thick lawn turf, fibrous weed stalks, and overgrown garden borders without bogging down the engine. The vibrant fluorescent yellow color ensures high visibility and accurate cutting tracking in all lighting conditions.

Key Features & Cutting Advantages

• Aggressive Square Profile (Ø 2.4 mm): Four sharp edges provide a superior scythe-like slicing effect compared to round lines, slicing clean through tough grasses and stubborn weeds with less resistance.
• Reduced Engine Load & Clean Cuts: Sharp slicing action reduces drag on the trimmer head, allowing the engine to operate smoothly at optimum RPMs while preventing frayed, yellowed grass tips.
• High-Tenacity Polyamide Material: Premium polymer structure resists tensile stress, repetitive impact against curbs and stone borders, and surface abrasion.
• High-Visibility Fluo Yellow Color: Enhances work-zone visibility, allowing operators to control trimming lines with precision along tree trunks, fences, and ornamental flower beds.
• Anti-Fusing Formulation: Specially treated surface prevents line welding and internal spool binding caused by high-friction heat during extended trimming sessions.
• Convenient Dispenser on Hanging Card: Handy 15-meter retail format equipped with a hanging slot for rapid reloading in the workshop or out in the field.

Usage & Storage Best Practices: To preserve elasticity and impact toughness, especially after prolonged storage in dry or heated rooms, submerge the line coil in water for 24 hours prior to loading into the trimmer head; water rehydration restores polymer flexibility and virtually eliminates eyelet breakage. Always wear certified safety goggles, heavy gloves, safety boots, and ensure the protective debris deflector is mounted securely to the machine.
