The Spinner Nozzle Spray Assembly is for use in holding pens that are 30 ft. wide or wider. Locate nozzles approximately 12 to 15 ft. on center for a good overlapping pattern, starting about 15 ft. back from the front of the holding pen. The Spinner nozzle only needs 4 to 5 ft. of clearance to get it's full pattern. It throws the water out and down from the nozzle. This assembly includes the green spinner plate assembly, a combination 20 psi pressure reducer and check valve with 1/2 in. FPT inlet, and a 2.6 gpm gold colored spray tip.
