The brushcutter head is universal: it fits most straight-arm brushcutters using the included screw or a blade mounting nut (not included). The nut is not included. The universal head is designed to accommodate nylon line up to 4.5 mm in diameter with round, square, or twisted profiles. It comes with four 3 mm diameter twisted nylon lines. Line replacement is quick and easy thanks to a system that allows for interference-free strand mounting (double strand tunnel). The head can be unscrewed by hand. The reverse thread rotation ensures the head never loosens. The body and base of the trimmer head are made of aluminum for exceptional strength and durability. In addition to the included nylon line, the trimmer head comes with: mounting reduction rings, a tightening rod for secure head installation, a 20mm inner diameter washer for proper head installation (machine side), and two washers with inner diameters of 8mm and 12mm for tightening the head according to the machine shaft diameter (internal head installation). Gardener's review: This trimmer head is very practical, saving time thanks to quick line changes. The aluminum construction is a major advantage in terms of longevity for both the head and the nylon line. This type of head allows for the installation of very strong and rigid strands. Technical specifications: Highly resistant aluminum; For installation with 2 or 4 wires; Compatible with wires up to 4.5 mm in diameter; Very quick wire change.
