Brand: K-Rain SKUs: FN-12F, FN-12H, FN-12Q
Product Overview
This selectable K-Rain FN 12-foot nozzle page includes fixed-pattern female-threaded spray nozzles in full-, half-, and quarter-circle configurations. Choose FN-12F for a nominal 360-degree full circle, FN-12H for a 180-degree half circle, or FN-12Q for a 90-degree quarter circle.
The female-threaded nozzles install on compatible male-threaded spray risers, including K-Rain Pro-S bodies and properly matched bodies from other manufacturers. Fixed arcs create repeatable pattern boundaries for corners, edges, and interior turf areas without requiring field arc adjustment. The nozzle family is color coded for field identification.
Flow is different for the full-, half-, and quarter-circle variants and also changes with operating pressure. The prior page applied a single quarter-circle label and one flow range to all three variants; use K-Rain’s performance data for the exact selected model and design pressure. Actual radius and precipitation depend on pressure at the nozzle, spacing, wind, elevation, and surrounding landscape conditions.

Frequently Asked Questions
Are all three patterns included?
No. Choose one variant from the selector.
Can a quarter-circle nozzle be adjusted to full circle?
No. Each variant has a fixed arc.
Do these fit K-Rain K-Spray bodies?
Standard K-Spray bodies use female risers for male-threaded nozzles. These FN nozzles are female threaded and require male-threaded risers such as Pro-S.
Why Buy These K-Rain FN 12-Foot Nozzles from Big Frog Supply?
Big Frog Supply lists every live arc separately and removes the old quarter-circle-only specification, helping customers match the intended coverage and calculate the correct zone flow.
