If you are purchasing this to replace the Paul C Buff softbox mounts please note it is approximately 2.5cm smaller. It won't fit exactly. I knew that before I bought it. I did preliminary research - I came across one that fits exactly not on Amazon but on a private site, it was three times the price of this one. In any case, don't worry, buy this product and replace Paul's plastic washers holding the mount with a slightly larger metal washer. Works great! Also note that this product comes from China, so please be patient with the delivery time.
