Some parts of the head are made of magnesium and other parts of aluminum. Virtually the entire head, including its knobs, is made of robust yet lightweight metal. A pan bar is included that can be attached to a rosette adapter on the left or right side of the head, for left- or right-handed users. A camera plate is included that can be adjusted forward/backward to let you find the optimal balance for your camera. A safety lock on the plate ensures that once mounted, the plate won't slip out if you move it in either direction too much. Two camera screws are supplied—1/4"-20 and 3/8"-16—that can be stored underneath the camera plate on the head itself, in dedicated slots. For attaching accessories, there's a 3/8"-16 threaded hole on each side of the head to which you can secure articulating arms.
