All compasses in the C-2300 series meet FAA TSO-C7c requirements. Each has been specifically designed for panel-mount installation on four holes (0.170” Dia.) equally spaced about a 2 5/8” mounting circle except for the C-2300-M23 models which have the lower mounting ears removed for increased frontal visibility. Wire lead length, voltage, and lighting color are specified under each stock number listed below. Each model is provided with a deviation card, deviation card window, and a deviation card-holder easily mounted near the compass for easy reference.
