The Rain Bird 1800 Series Professional Pop-Up Sprinkler is the #1 commercial-grade irrigation spray brand in the world. Installed in parks and yards across the globe it is chosen for its reliability, heavy-duty materials and versatility. Precision spray heads and nozzles customize your watering system to cover virtually any configuration of lawn or garden - not the sidewalk or driveway. The 1800 Series has first-rate quality built in for reliable operation and long life. 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 a heavy-duty stainless steel spring to assure flush retraction every time. An exclusive co-molded wiper seal provides unmatched resistance to grit, pressure and the environment. A tapered pop-up neck helps to assure retraction in all soil types. The pre-installed Adjustable Pattern Spray Nozzle is easily adjusted to the exact pattern required to ensure your landscape is precisely watered with minimal overspray. 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. Non-corrosive plastic and stainless steel construction provides a long life. A simple stainless steel top adjustment screw decreases or increases spray distance. A mesh filter screen protects the nozzle from clogging and maintains precise radius adjustment. No tools needed to change nozzles. Operates efficiently at low water pressure; 1/2 inlet size.
