The Profoto OCF Speedring is used for mounting an OCF Softbox or an OCF Beauty Dish on your off-camera flash. It is not your everyday speedring, though. Not only is it more compact and lightweight, but the patent-pending design allows you to snap on the softbox or beauty dish without having to bend and fumble with the rods, while the clever color codes show you exactly how to assemble the unit. The classic Profoto rubber collar and clasp make it easy to mount the OCF Speedring on the off-camera flash.
