Rain Bird 5000/5000 Plus MPR Nozzles simplify both the design process and the installation of rotors, because they reliably deliver matched precipitation rates within and between rotor radii from 25' to 35'. Without having to use fixed arc plates, designers and installers can achieve MPR using either 5000 Series or 5000 Plus Series Rotors. Superior flexibility in arc adjustment minimizes the risks of over or under watering.
