Brand: K-Rain SKUs: FN-15CS, FN-15H, FN-15Q, FN-15SS, FN-15ES, FN-15F
Product Overview
This selectable K-Rain FN15 page includes female-threaded fixed spray nozzles for compatible male-threaded risers. The circular-pattern choices are FN-15Q quarter circle, FN-15H half circle, and FN-15F full circle. Specialty choices include FN-15CS center strip, FN-15ES end strip, and FN-15SS side strip.
The standard circular models are commonly described as 15-foot nozzles, but actual radius changes with pressure. K-Rain’s performance data shows approximately 13 feet at 20 PSI, 16 feet at 30 PSI, and 17 feet at 40 PSI. The strip models use rectangular patterns rather than a circular radius: the center strip is approximately 4 by 24 feet at 20 PSI and 4 by 30 feet at 30 PSI; the end strip is approximately 4 by 12 feet at 20 PSI and 4 by 15 feet at 30 PSI; and the side strip is approximately 4 by 28 feet at 20 PSI and 5 by 32 feet at 30 PSI.
Each variant has a fixed arc or pattern and is supplied as a nozzle component rather than a complete spray body. Select the exact SKU needed for the landscape shape and calculate zone demand from the corresponding performance row. The live selector may label FN-15CS as “Corner Strip,” but the manufacturer SKU identifies it as the center-strip pattern; the variant itself has not been changed.

Frequently Asked Questions
Are the strip models 15-foot circular nozzles?
No. Strip nozzles produce rectangular patterns with model-specific width and length.
Does FN-15CS mean corner strip?
K-Rain identifies SKU FN-15CS as the center-strip pattern, even though the current store selector may display a legacy Corner Strip label.
Do these fit 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 FN15 Nozzles from Big Frog Supply?
Big Frog Supply identifies every live SKU by its actual thread type and coverage geometry, including the legacy FN-15CS selector-label issue, so customers can match the right fixed arc or strip pattern without treating every option as the same 15-foot circle.
