The Rain Bird 24RNFPRO (W22103) high efficiency rotary nozzle offers water savings of up to 30% over a standard pop-up spray nozzle. It covers a distance from 17-24 feet with a 360 degree full watering pattern. Rotating streams of large water droplets reduce runoff and provide uniform coverage, even in windy conditions. The 24RNFPRO can replace your current pop-up full pattern spray nozzles to start saving water. To clear debris that may block part of the nozzle simply pull up the nozzle while water is running, and the debris will be flushed out. Replacement nozzle for item # 259845 and 271972 spray heads.
