It features a dual spray nozzle configuration with patented close-in watering technology that promotes uniform water coverage and reduces dry spots across turf and landscaping zones. The 4-inch pop-up height suits standard lawn installations, and the 1\/2-inch inlet connects to common lateral line fittings. A patented pressure-activated co-molded wiper seal keeps the riser clean during retraction, extending service life in gritty soil conditions. Licensed irrigation technicians and landscape professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis spray head is suited for residential lawns, commercial turf areas, and landscape beds requiring full-circle coverage. The dual spray nozzle delivers even distribution from the center of the arc outward, addressing the dry-ring problem common with single-nozzle heads. The removable grit filter protects the nozzle orifice from particulate contamination in municipal and well-water systems alike. The unit ships in a package quantity of 18, making it practical for zone-level installations where multiple heads are replaced at once.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePatented close-in watering dual spray nozzle for uniform full-circle coverage and elimination of dry spots\u003c\/li\u003e\n  \u003cli\u003ePressure-activated co-molded wiper seal keeps riser clean on retraction\u003c\/li\u003e\n  \u003cli\u003eStainless steel retractable spring ensures consistent pop-up and retraction over the service life of the head\u003c\/li\u003e\n  \u003cli\u003eStainless steel flow-control reduction screw allows arc and radius adjustment without specialty tools\u003c\/li\u003e\n  \u003cli\u003eRemovable grit filter protects nozzle from particulate debris in the water supply\u003c\/li\u003e\n  \u003cli\u003eEasy nozzle alignment feature simplifies field installation and nozzle swaps\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation spray head for standard 1\/2-inch threaded irrigation lateral lines in residential and commercial pop-up spray zones.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed irrigation technicians or qualified landscape contractors. Shut off the irrigation zone and relieve line pressure before removing an existing head or threading in the new unit.
