An impact sprinkler is a time-tested way to efficiently distribute water across a medium to large area, with an adjustable 30-to-360-degree pattern. The plastic impact sprinkler head with weighted arm ensures slow rotation and long distance under higher pressures. A spray deflector shield and adjustment screw allow for precise radius adjustment from 25 ft. down to 15 ft. at typical operating pressure of 40 PSI. A common application for this head is to mount it on a spike, ring base, or Schedule 40 or 80 PVC coupling. For outdoor irrigation use with cold water only.
