4'' Pro-S Spray with pre-installed 80 to 360 degree Fully Adjustable Rotary Nozzle with a radius of 13' to 15'.

The Pro-S™ Spray is designed to provide long life and outstanding performance. The result of precision engineering and extensive field testing by contractors around the world. These sprays are distinguished by robust construction, rugged body and cap, co-molded seal and heavy-duty retraction spring. Built with the contractor in mind. The co-molded wiper seal ensures proper operation time after time with minimal flow by.

The K-Rain® Fully Adjustable Nozzles use up to 30% less water and are eligible for conservation rebates and incentives in many areas.

No other nozzle on the market today is fully adjustable from 80° to 360° degrees offering maximum flexibility in system design and eliminating the need for multiple nozzles. One nozzle does it all. Assembly fits in a Rain Bird® 1800 Series spray body.
