Add-on Side Shelf, Vision Isostation, 30 in., Requires VIS-SSH-30

VIS-SSA-30 is an additional shelf that mounts to VIS-SSH-30, so that user may have more than one level of storage. It does not include the vertical supports so it can not be directly mounted to the workstation. It is recommended for users who own VIS-SSH-30 and want to increase their storage capacity vertically along the supports.
