K-Rain RN Adjustable Rotary Nozzles, 80°–360°
Brand: K-Rain | SKUs: RN100-ADJ, RN200-ADJ, RN300-ADJ
Product Overview
This selectable K-Rain RN family includes adjustable rotary nozzles for three distance ranges. Each model adjusts by hand from 80° to 360° and uses multiple rotating streams to apply water more slowly than a conventional spray nozzle. The female-threaded connection fits K-Rain Pro-S, NP, and other compatible spray bodies with male-threaded risers.
Choose the variant by the required coverage distance: RN100-ADJ for approximately 13–15 feet, RN200-ADJ for 16–19 feet, or RN300-ADJ for 26–30 feet. Before ordering, confirm the thread style, dynamic pressure, total zone flow, required radius, and precipitation rate of the other nozzles on the zone. The spray body is sold separately.

Compatibility & Installation Notes
Confirm that the spray body has a male-threaded riser and can provide the selected model’s required flow near 40 PSI. Rotary nozzles generally should not share a zone with conventional sprays unless precipitation rates are intentionally matched. Flush the body before installation and verify head-to-head coverage after setting the arc and radius.
Frequently Asked Questions
Are these RN nozzles limited to a 90°–270° arc?
No. The current RN100-ADJ, RN200-ADJ, and RN300-ADJ models adjust from 80° to 360°.
Will these nozzles fit K-Spray bodies?
No. Standard K-Spray bodies use female risers; these nozzles are also female threaded and require a male-threaded riser.
Is a spray body included?
No. The selected nozzle and filter are included; the compatible body is sold separately.
Can rotary and conventional spray nozzles share a zone?
Only when their precipitation rates and hydraulic requirements have been intentionally matched.
Why Buy K-Rain RN Adjustable Rotary Nozzles?
Big Frog Supply keeps the three current distance ranges together and organizes the thread, pressure, arc, and radius details so homeowners, contractors, and maintenance teams can compare each RN SKU before ordering.
