The Profoto RFi Speedring (Part #100501) is the essential adapter that allows you to mount any Profoto RFi Softbox(like the 3x4', 1x6', or 4' Octa) onto a Profoto flash head. Unlike the OCF speedring, which is made of lightweight plastic for portable flashes, the RFi speedring is constructed from high-strength metal to support the weight of larger, professional studio modifiers.

Product Details:
