Constructed from heavy-duty iron casting, the Kupo Swivel Junior Receiver Adapter comes with a male 1-1/8" pin ( 28mm) at one side designed to drop into a combo stand junior receiver. Also features a swivel female 1-1/8" receiver at the other end with a rosette mechanism that allows for a tilting angle every 30 degrees. Ideal for rotating a fixture, such as the Arri Skypanel, from horizontal to vertical and eliminating interference of barn door/softboxes when positioning a light on the stand..
