The 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 makes it easy to mount the OCF Speedring on the off-camera flash.
