Installed in parks and yards across the globe, Rain Bird's 1800 Series is the #1 commercial-grade irrigation spray head brand in the world. Chosen for its reliability, heavy-duty materials and versatility, the 1800 Series has first-rate quality built in for reliable operation and long life. Superior components and features make them the spray heads of choice for a wide variety of applications. This sprinkler’s Matched Precipitation Rate allows it to be used in any combination with other Rain Bird fixed and adjustable pattern sprays. Additional 1800 Series features include: Heavy-duty stainless-steel spring to assure flush retraction, every time. Exclusive co-molded wiper seal features an encased plastic "cage" to provide unmatched resistance to grit, pressure and the environment. Pressure-activated, multi-function seal design assures a positive seal without excess “flow-by” allowing more heads to be installed on the same valve. Tapered pop-up neck helps remove debris during retraction while a precision controlled flushing action also clears debris to assure positive stem retraction in all soil types. Two-piece ratchet mechanism on all models allows easy nozzle pattern alignment without tools and provides extra durability. All sprinkler components are removable from the top without special tools; providing for quick and easy flushing and maintenance. Spray Nozzle details: The preinstalled Adjustable Pattern Spray Nozzle is easily adjusted to the exact pattern required to ensure your landscape is precisely watered with minimal overspray waste. Ideal for odd-shaped corners and smaller grassy areas around sidewalks and driveways as well as flower beds or shrubs. The textured adjustment collar rotates to easily adjust spray pattern from 0° to 360°. Textured base and collar are easy to grip even when wet. A physical left edge indicator makes it easier to feel the fixed left edge of the pattern. Non-corrosive plastic and stainless-steel construction for long life. Simple stainless-steel top adjustment screw decreases or increases spray distance from 6' to 8'. "Captured" screw slot prevents screwdriver slippage during adjustment. White medium mesh filter screen protects nozzle from clogging and maintains precise radius adjustment. No tools needed to change nozzles. 1/2" inlet size.
