One & Two Meter Long Risers.
Long risers come in one and two meter lengths. These can be used with the wider base K-Line Irrigation "mid" sized pod. The long risers are designed to get the sprinklers up high (over 6 feet) for taller crops being irrigated. Click on the link below to see a demonstration of these being used in corn.
These long risers also have an application in nursery's where a semi-permanent sprinkler with some height is required.
