Know before you buy
The stainless steel riser provides superior durability and strength compared to plastic alternatives. It is specifically designed to resist vandalism and withstand the wear and tear of harsh environments or high-traffic areas.
Yes, each unit includes a set of 12 nozzles—8 standard and 4 low-angle—along with the necessary rotor adjustment tool. You will just need to ensure you have the correct 3/4-inch FPT fitting for your irrigation line.
FloStop allows you to shut off the water flow at the individual head without turning off the entire irrigation system. This makes it much easier to perform nozzle changes or routine maintenance on a single unit.
Yes, the I-20 features through-the-top arc adjustment, allowing you to easily fine-tune the spray pattern from 50º to 360º using the included tool, even while the system is running.

The I-20-04-SS has a versatile radius range of 17 to 46 feet, depending on the nozzle selected and your water pressure. It is designed to operate efficiently within a recommended pressure range of 25 to 70 PSI.
