The Profoto RFi Speedring Adapter for Nikon / Canon comes with a solid aluminum softbox collar. The collar mounts to your light with a mounting flange, custom for your specific brand of light. When using square or rectangular softboxes, rotating the box offers additional control. Luckily, all Profoto RFi Speedring Adapters offer 360 degree of rotation so regardless of which softbox you are using or what brand of flash you are using, full control is possible.
