The PGJ was built to bring all the efficient benefits of rotary sprinklers to applications that typically call for a spray. Its many features include a rack of easy-to-install-and-change, water-efficient nozzles, easy arc adjustment, and all the safety and durability that comes with a rubber cover. The PGJ is capable of working in tandem with larger rotors to combine big and small areas in a single zone, offering a convenience and efficiency that sprays do not. When used in the right application, the PGJ allows fewer heads to perform more efficiently at a more economical price. Arc setting: 4 to 36 degrees Nozzle choices: 8 Nozzle range: .75 to 5.
