Trimmer line Polax Square with Cord 3 mm x 15 m, reinforced cutting cord

Polax Square with Cord reinforced trimmer line, 3 mm diameter and 15 m length, is a square-profile cutting cord with an internal nylon core designed for garden grass trimmers and brushcutters that accept 3 mm line. The square cross-section provides sharp edges for efficient cutting, while the internal cord increases tensile strength and wear resistance. This line is intended for cutting dense grass and light brush and gives stable cutting performance with improved durability compared with standard round lines.

Advantages

The reinforced construction combines a durable outer nylon sheath with a PA.66 nylon core to enhance resistance to abrasion and breakage. The square profile delivers straight, precise cuts and maintains performance on tougher vegetation. High flexibility reduces strain on the trimmer head and contributes to lower operating noise. Available in 15 m length, the line is easy to load and suitable for common consumer and light professional outdoor tools.

Suitable for

• Cutting dense grass and lawn edge trimming
• Light brush and weed clearing
• Use with electric and gasoline trimmers that accept 3 mm line
• Garden maintenance on uneven or stony terrain

How to use

Choose the 3 mm line for trimmers and brushcutters specified to accept 3 mm diameters. Power off the tool and follow the manufacturer’s instructions to open the cutting head or spool. Measure and wind the 15 m line onto the spool according to the rotation direction indicated on the spool, leaving the recommended free ends for fastening. Reassemble the head, secure any retaining parts, and test at low speed to confirm proper feed and balance before regular operation.

Usage recommendations

For longevity, avoid striking large rocks or hard obstacles at full speed and replace worn sections promptly. For equipment selection: electric trimmers and gasoline trimmers with engine displacement around 25–33 cm3 typically use lines up to 2.4 mm; gasoline trimmers with higher power around 33 cm3 are suitable for 3 mm line. Store the line in a dry, cool place away from direct sunlight to prevent material degradation.
