This product is designed for use with electric and petrol strimmers/trimmers to cut grass, weeds, and brambles. The line has a twist finish, providing a larger cutting surface for a cleaner cut and reducing the time spent on longer grass. Additionally, it produces less noise, making it more pleasant for you and your neighbors. The line comes in a 15m length and can be manually wound onto your existing spool, making it more environmentally friendly by avoiding waste. Please consult your manual to ensure you use the correct cord size for your strimmer. For safety, always unplug the strimmer before changing the cord and wear protective footwear and safety glasses. We offer this line in five sizes: 1.6mm, 2.00mm, 2.4mm, 2.7mm, and 3mm.
