This half-circle unit features a dual spray nozzle configuration with patented close-in watering technology that promotes uniform water coverage and reduces dry spots. The 1804HDS pops up 4 inches for adequate throw clearance above turf and ground cover. A patented pressure-activated co-molded wiper seal keeps the stem clean on retraction, extending service life in sandy or dirty soil conditions. Irrigation technicians and landscape contractors install this head where consistent arc coverage in tight or bordered zones is required.\u003c\/p\u003e\n\u003cp\u003eThe 1804HDS is suited for half-circle coverage zones in residential lawns, commercial turf areas, and landscaped beds where a 180-degree spray pattern is needed.
