K-Rain SuperPro rotors are designed with a patented flow shut-off which will make installations simpler and drier. The K-Rain SuperPro is perfect for construction areas – newly laid sod can be watered, and areas awaiting sod can be shut off until the sod is laid. K-Rain SUPERPRO sprinkler heads are packed with innovative features, such as partial to continuous 360° coverage; interchangeable nozzles for matched precipitation; and the patented Easy Arc Set and Arc Memory Clutch.
