The RS 850 tubular column system comes with 3 m, 6 m or 9 m columns as standard, with standard pipeline lengths. Different tubular columns for setting up the boom pedestal and arm assembly are not required. The double M tubular column profile requires only one simple, square cut-out (1 m x 1 m) in the floors. By using an adapter, existing booms can continue to be used with the RS 850 tubular column.
