K-Rain's RPS® Select rotary sprinkler is the first gear-driven sprinkler that makes matched precipitation fast and easy, without the need to change nozzles in the field. It offers a choice of 4 selectable built-in nozzles. With a twist of a flathead screwdriver, quickly select the correct nozzle to match the arc setting of the sprinkler or landscape. No nozzle trees to carry or lose. Using a combination of the four nozzles, it's easy to achieve matched precipitation across all arc settings. The four built-in nozzles also make RPS® Select a convenient universal replacement sprinkler for other brands.
