These Low Pressure, 1/2" Side Mount Hurricane 80 Sprinklers are designed for municipal water type connections. They operate at 40-120 psi of water pressure and have a 70' max spray diameter. They come with a billet aluminum mount that will attach to most flat surfaces using 3 stainless steel screws to securely mount it. Easily removed by sliding the sprinkler out of the billet aluminum bracket. Commonly used on wood fences, posts and under decks to slow wildfire spread. They can also be operated on some of our FLD System pumps under higher pressures. The option of an adjustable sprinkler head adds the flexibility to allow you to direct the outgoing stream of water in a limited spray pattern, under use conditions when a full 360º radial spread isn't optimal, such as when mounted up against structures or property lines.
