For Interpro Series 3 tripods. The circular camera platform can be used flat as is, (note: center column must be removed) or with either the #G540 or #G541 right angle bracket.
Lateral arms enable cameras to be positioned above or below the tripod in a 90 degree position, which might otherwise be obstructed by the tripod legs. They are available in rapid and geared versions and include a reversible 1/4 and 3/8" mounting stud.
