What tread size is the bracket?
The bracket have a “professional” tripod tread, this is the thick 3/8th tread version used several places, you can mount the bracket directly to the center collum of most tripods, or you can use a adaptor from 1/4th inch tread to 3/8th tread, this is sold in most photostores, I recomend using one of the tall “stud” style ones, which have a tread in the bottom and a screw on the top, this will help you bring the camera away from the size of your tripod head.
