Disclosed is an inclined mobile screen for processing road building materials which provides for easy reconfiguration of the screen from operation configuration to a transport configuration and to a maintenance configuration, which allows for increased clearance between the screen and a feed conveyor without requiring a hydraulic actuator disposed therebetween. Nested telescopic supports are selectively coupled together in an offset connection to allow changes in the orientation of the screen to result in changes in the separation between the screen and the conveyor so as to allow for more clearance therebetween during time of maintenance.
