A handy instrument to firmly hold the expander. It allows easy and accurate modelling of the arms, together with the special arm bending tool P1620-02. The instrument ends with a clutch mechanism that is shaped on the model of the expander to avoid damage to the bodies, and stays closed by a cursor clamp device turned on and off with a simple thumb action.
The edge thickness of the clutching mechanism ends is designed to indicate the minimum space between the body of the expander and the palatal vault. By placing the instrument with the screw on the plaster model, the correct inclination and the right height to bend the arms become clearly visible. It is also useful to test the expander prior to use, by opening and closing it with the special straight key.
