Once you have determined the Kieninger movement pendulum requirement from the movement brass plates, the next step is to select the overall pendulum finish, rod style, and bob (disk) size.
The typical pendulum finish options are polished brass, brushed brass, chrome (shiny silver), and brushed nickel.
The rod style options are straight rods or twisted and straight.
The appropriate bob disk size is determined by the size of the clock case. If the bob disk is too large, it will hit the sides of the case.
