Brand: K-Rain SKUs: RN100-ADJ, RN200-ADJ, RN300-ADJ
Product Overview
This selectable K-Rain rotary-nozzle page includes the current fully adjustable RN100, RN200, and RN300 models. Each nozzle adjusts by hand from 80° to 360°, allowing one SKU per distance range to serve corner, side, irregular, and full-circle locations. The nozzles use female threads for K-Rain Pro-S, NP, and other compatible spray bodies with male-threaded risers.
Multiple rotating streams apply water more slowly than a conventional spray nozzle, improving wind resistance and allowing more time for soil absorption. K-Rain designs the family for matched precipitation through arc and radius adjustment, and the patented flow control permits radius reduction of up to approximately 30%. A double-pop-up mechanism helps protect the rotating components from dirt, while the large removable filter supports cleaning and service.
K-Rain recommends approximately 40 PSI for normal rotary-nozzle performance. Choose the model by the required distance range: RN100 covers approximately 13 to 15 feet, RN200 covers 16 to 19 feet, and RN300 covers 26 to 30 feet. Actual coverage depends on dynamic pressure, installation height, wind, slope, and spacing. These are nozzles only; spray bodies and pressure regulation are sold separately.

- Irregular turf areas requiring broad arc adjustment
- Pro-S and NP spray bodies with male-threaded risers
Compatibility and Installation Notes
Confirm the spray body uses a male-threaded riser and that the zone can supply the selected model's total flow at approximately 40 PSI. Rotary nozzles generally should not share a zone with conventional spray nozzles unless the precipitation rates are intentionally matched. Flush the body, install the filter and nozzle, set the left and right arc limits, and verify head-to-head coverage.
Frequently Asked Questions
Are these models limited to 90°-270°?
No. RN100-ADJ, RN200-ADJ, and RN300-ADJ are the current fully adjustable 80°-360° models.
Will they fit K-Spray bodies?
No. K-Spray has a female riser; these nozzles are also female threaded and require a male riser.
Is a spray body included?
No. The selected rotary nozzle and filter are included; the body is sold separately.
Why Buy This K-Rain Fully Adjustable Rotary Nozzle from Big Frog Supply?
This page keeps all three current distance ranges together and corrects the legacy 90°-270° title language for these exact ADJ variants. Big Frog Supply also carries compatible Pro-S bodies, pressure-regulated models, nozzle guards, and legacy fixed-arc rotary nozzles for matching existing systems.
