The height of the HKS magnet system from the common base is 3.2 m and it will be placed on the platform prepared by Jlab. It is designed so that the spectrometer system can be installed either in Hall C or Hall A where the beam heights are 396.24 cm (13') and 304.8 cm (10'), respectively. The D magnet is supported by three legs which stand on the platform. The spectrometer position is hydraulically adjustable in 3D. The Q1 and Q2 magnets are placed on a girder stuck from the side of the D magnet. The center of mass is not expected to shift much by this connection because the D magnet is much heavier than Q1 and Q2.
