Secondary Nozzle

Improve the uniformity of solid set Big Gun® systems by applying water in-close around the sprinkler.


For solid set Big Gun® systems the uniformity can be improved by using a secondary nozzle. The secondary nozzle is especially beneficial when sprinklers are spaced further apart than head-to-head. The nozzle should be sized to deliver approximately 10% of the primary nozzle flow rate.

  • F75/F100: A 7/32" 3RN nozzle is most common
  • SR100/SR150 use secondary nozzle kit #9724, which includes 5/16" (SR150) & 7/32" (SR100) 3RN nozzle and elbow
  • F150: A 5/16" 7RN nozzle is most common
