STIHL Quiet Line™ incorporates spiral grooves  in the design that greatly reduces trimming noise. The indentations in the surface of the line interrupt the otherwise uniform air stream, reducing the whistling effect. This trimmer line is recommended for use with corded-electric and battery-powered line trimmers, which operate much quieter than gasoline-powered models. Use this trimmer line when working on properties with noise restrictions. 

Features:  

• Color-Coded - Nylon lines are color-coded to easily define the diameter of the cutting line. STIHL offers trimmer lines in all standard sizes including .065 (blue), .080 (light green), .095 (orange), .105 (red), and .160 (dark green) diameters. 
• Variations Available - This product is available in a variety of sizes and configurations. 
• Quiet Operation - This product is ideal for noise-sensitive areas. 

STIHL professional tip - leave your new mowing line in water for 24 hours before use. This will increase the flexibility and lifespan of the mowing line.
