Rain Bird 12DSH Dual Spray Nozzle Half Circle 9-12 Ft

Product Description

The RAIN BIRD 12DSH is a half-circle dual spray nozzle designed for residential and commercial irrigation systems. It features two spray orifices that deliver improved close-in coverage and more uniform water distribution across the full 180-degree pattern. The stainless-steel adjustment screw controls both flow rate and spray distance, allowing field adjustment between 9 and 12 feet and flow from 1.8 to 2.6 gallons per minute (GPM). A patented undercut design reduces water use by approximately 30 percent and limits drift in windy conditions. Landscapers and irrigation technicians install this nozzle where consistent precipitation rate and turf coverage near the head are critical.

The 12DSH is suited for residential lawns, commercial turf areas, and landscape beds where a 180-degree spray pattern is required. The matched precipitation rate design integrates with mixed-nozzle zones, keeping watering times consistent across the system. A fine mesh filter screen protects the orifices and maintains accurate radius performance over time. The nozzle fits all Rain Bird pop-up sprinkler bodies and shrub adapters, making it a direct drop-in for retrofit and new-install applications alike.
