The adjustable pattern spray nozzle is engineered to deliver uniform droplet sizes across a 0-to-360-degree arc. It includes a filter and adjustment screw which allows you to reduce the spray pattern down to 75 percent of its rated distance. Its low-angle trajectory helps improve efficiency by minimizing wind drift. The male inlet threads are compatible with Toro spray heads. The adjustable pattern nozzle is available in 4, 8, 10, 12, 15 and 18-foot radius versions, each with a color-coded body for fast identification. For optimum efficiency pair the adjustable pattern spray nozzle with a professional series pressure regulating spray body set at 30 PSI. For outdoor irrigation use with cold water only.
