Each turnout requires a BullFrog Manual Turnout Control and a BullFrog Control Rod Kit, either 18" or 36", depending how far the BullFrog will be located from the control location. If the BullFrog will be more than 36" away then you will need additional lengths of Control Rod that come in 18" and 36" lengths.
For long runs of Control Rod you may also need a Control Rod Joiner/Hanger Support Kit to support each control rod joint. There are other BullFrog accessories for special applications that can be found here.
