The tripod already puts the center column at 90 degrees, min height is 3.5”. Undo the screw, lift the column all the way and press the small button at the base of the column, list until it passes the collar and it will then tilt to,90 degrees and you can run it in or out as needed. There Is even a 90 degree adapter to get your head back to ‘normal’ orientation, I use that with my gear head for example.
