Compatibility & Installation Notes
Flush the spray body before fitting the nozzle and screen. Match the fixed arc to the head location, then check available pressure and zone flow. Rain Bird recommends no more than 25% radius reduction. Published performance assumes zero wind and testing on a 4-inch pop-up; coverage is not the nozzle's physical size. Spray body is purchased separately.
Frequently Asked Questions
Which RB15 option should I choose?
Choose RB15F for a full circle, RB15H for a half circle or RB15Q for a quarter circle.
Can I adjust the arc?
No. These are fixed-pattern nozzles; the screw adjusts radius and flow rather than changing the arc.
When does it reach 15 feet?
The published radius is 15 feet at 30 psi. Lower listed pressures produce a shorter throw.
Why Buy from Big Frog Supply?
Choose RB15 for a layout designed around a 15-foot radius at 30 psi. Full-, half- and quarter-circle options draw 3.70, 1.85 and 0.92 gpm respectively, so select both the coverage shape and the matching flow when sizing the zone. The black top helps identify the series during service.
