Actuators keep the Clamp Ribs evenly spaced and align them with the Mandrel.
The Actuator is threaded onto and then pinned to the Draw Rod. It captures one end of the Clamp Ribs in a slot that permits them evenly expand and contract when the Draw Rod Wench is activated and they interface with the taper on the Mandrel. Three Actuators are available for the Wart and the one you need depends on the Mandrel size. The G Series Clamp Ribs use G-17, the H-00 Clamp Ribs use the H-12A and the H-01, H-02, H-03 and H-04 Clamp Ribs use the H-12 Actuator.
