Can you mount the Center Mast Bracket to the Apollo or Voyager?

Yes! The Center Mast Bracket can be mounted to the Threaded Rail Plates of the top shelf and/or to the workstation carts Accessory Crossbars. Please do not mount 3rd party products weighing in excess of 5lb to Voyager Rail Plates. Apollo Rail Plates can hold conisderably more weight, up to 20lb. Nevertheless, be cautious of what you're mounting. If the top shelf flex's easy with the item mounted to the Rail Plate, the item is too heavy for this application.
