The Spinner Nozzle Spray Assembly is for use in holding pens that are 34 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 2 to 3 ft. of clearance to get it's full pattern. It throws the water out and up slightly to acheive the full pattern even with limited clearance. This assembly includes the gray spinner plate assembly, a combination 30 psi pressure reducer and check valve with 1/2 in. FPT inlet, and a 2.5 gpm red colored spray tip.
