A modular support column allows electrical signal-and-power-transmitting lines between a data-processing device and an associated weighing device to be enclosed. The modular support column includes a foot module, at least a primary pole module, at least one adapter module to connect one of said data processing devices to the modular support column, mechanical connector elements and fasteners to secure the modules to each other. The modular support column, when assembled, has a centeral axis defining an axial direction. A first axial end of the primary pole module is connected with the foot module which, in turn, is to a chassis base of a weighing scale. A second axial end is connected with the at least one adapter module. The mechanical connector elements and fasteners are also enclosed. Extension pole modules and adapter modules can extend the modular support column.
