This new feature allows you to remove the centre column to save weight and get the camera closer to the ground. Uses existing components: the upper disc with reversible 1/4'' - 3/8'' bolt and the column hook assembly: Remove column and fix the disk directly to the upper casting using the column hook. No tools needed.
This built-in accessory allows you to hang a stabilizing weight (e.g. a full camera bag or a sand/water bag) from the bottom of the tripod centre column. Useful with long/heavy lenses, on uneven ground or in windy conditions.
