Photos show the following: First for illustration purposes only, the Alfae tripod with a Gitzo G525 Rapid Column installed. As mentioned the Alfae and Gitzo series 4 & 5 column parts are inter-changable. Also showing 18 1/4 inch elevating column installed as a side-arm. Very handy for macro work. Finally the last photo shows the 85mm Diameter Top Plate with 3/8 inch stud. This plate installed only, lightens the tripod's weight down to 9.74 lbs.
