These ultra hight-powered Rooftop Hurricane 270 Sprinklers are designed to be mounted on a rooftop and used with our 120-140 psi high-pressure, high-volume FLD Pump Systems, giving you the largest coverage of up to 240' in diameter spray. These custom, extreme duty, weighted sprinklers are built of steel and will reduce accidentally sliding or moving, even under high pressure. These rooftop sprinklers have a high angle trajectory enabling a spray coverage of up to 240' foot in diameter from one sprinkler head (great for larger properties), shielding your structures as well as the surrounding vegetation from approacing wildfire.
