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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual spray orifices provide superior close-in watering and reduce dry spots near the head\u003c\/li\u003e\n  \u003cli\u003ePatented undercut design uses approximately 30 percent less water and resists wind drift\u003c\/li\u003e\n  \u003cli\u003eAdjustable spray distance from 9 to 12 feet via stainless-steel set screw\u003c\/li\u003e\n  \u003cli\u003eFlow rate adjustable from 1.8 to 2.6 GPM\u003c\/li\u003e\n  \u003cli\u003e180-degree half-circle pattern at a 23-degree trajectory\u003c\/li\u003e\n  \u003cli\u003eCaptured screw slot prevents screwdriver slippage during adjustment\u003c\/li\u003e\n  \u003cli\u003eFine mesh filter screen maintains precise radius performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with all Rain Bird pop-up sprinkler bodies and shrub adapters.
