Permanent solid set systems are stationary and cannot be moved. Permanent systems require less labor because they are not being moved and usually require less maintenance for the wear that moving entails. We see many of these systems in tree crops, vineyards, and sometimes open field applications. The selection of products to be used in permanent solid set depends on the application. Products can vary from Big Gun sprinklers used with valves to smaller Rotator products such as the R2000WF, R10, R10T and R2000.
