## Summary description

STIHL square trimmer line with a 2.4 mm diameter and 434 mm length, designed for use in compatible STIHL grass trimmers and brushcutters. The square profile improves cutting efficiency on grass and light weeds, providing precise trimming along edges and around obstacles. Suitable for garden maintenance, edging and light vegetation control.

## Long description

STIHL square trimmer line, 2.4 mm diameter and 434 mm length, is engineered for compatible STIHL grass trimmers and brushcutters. The square-profile cutting line offers improved cutting performance on grass and light weeds compared with round lines of similar diameter, enabling accurate edging and controlled trimming around flower beds, fences and paths. This trimmer line is intended for routine garden maintenance and small-scale vegetation control where a balance of precision and durability is required.
Advantages
The square profile increases the cutting edge contact area for cleaner, straighter cuts on turf and thin-stemmed weeds while maintaining a compact 2.4 mm thickness that fits many STIHL trimmer heads. The 434 mm length provides a practical replacement segment for spool-style and fixed-line systems designed to accept this format. Manufactured to STIHL specifications, the line delivers consistent diameter and profile for predictable performance and reduced vibration during use.
Suitable for
Trimming grass and light weeds in domestic gardens
Edging around lawns, pavements and flowerbeds
Detail work close to obstacles such as fences, trees and garden furniture
Routine garden maintenance and seasonal clean-up tasks
Key specifications
Profile: square
Diameter: 2.4 mm
Length: 434 mm
Material: high-strength nylon (engineered for cutting line use)
Compatibility: designed for use with compatible STIHL trimmer heads and brushcutters that accept 2.4 mm line
How to use
Turn off the trimmer and disconnect the spark plug or power source before replacing the line. Remove the trimmer head cover according to the trimmer manufacturer’s instructions, then insert the square trimmer line into the spool or fixed holder following the orientation required by the head. Wind or position the line evenly to avoid tangling, replace the cover and tension or lock the line as specified. Restore power and test cutoff at low throttle before normal operation.
Usage recommendations
Use the STIHL square 2.4 mm line for routine trimming and precision edging rather than heavy brush or thick-stemmed vegetation. For thicker stems or dense undergrowth, select a heavier line or appropriate cutting attachment. Regularly inspect the line for wear and replace when fraying or significant diameter reduction is observed. Follow all safety guidelines in your trimmer manual, wear appropriate protective equipment, and keep bystanders clear while operating.
