It features a 4-inch pop-up height and an adjustable spray pattern ranging from 0 to 360 degrees, making it adaptable to a wide range of zone layouts. The spray distance reaches up to 4 feet. A patented pressure-activated co-molded wiper seal keeps the riser clean and extends service life. A stainless steel retractable spring ensures reliable retraction after each cycle. Licensed irrigation contractors and landscape professionals are the typical installers of this head.\u003c\/p\u003e\n\u003cp\u003eThe 1804AP4 is suited for turf and groundcover zones in both residential and light commercial irrigation applications. Its 1\/2-inch inlet is compatible with standard lateral pipe connections used in low-volume spray zones. The adjustable arc makes it practical for irregular or corner areas where fixed-pattern heads would create overspray or dry spots. The removable grit filter helps protect the nozzle in systems with moderate sediment loads, reducing service calls. Easy nozzle alignment allows for quick field adjustment without specialty tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch pop-up height for turf clearance and clean retraction\u003c\/li\u003e\n  \u003cli\u003eAdjustable arc from 0 to 360 degrees to match any zone shape\u003c\/li\u003e\n  \u003cli\u003eSpray distance up to 4 feet\u003c\/li\u003e\n  \u003cli\u003ePatented pressure-activated co-molded wiper seal for extended seal life\u003c\/li\u003e\n  \u003cli\u003eStainless steel reduction screw and retractable spring for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eRemovable grit filter protects nozzle from sediment\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch inlet for standard lateral connection\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 residential and commercial low-volume irrigation spray zones using 1\/2-inch threaded lateral connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed irrigation contractors or qualified landscape professionals.
