Centering up the flash

I like shooting with an umbrella, bounce or shoot through. They are light weight, easy to setup and take down. What I don’t like is that the flash set so high above center of the umbrella. So, I dug through my junk drawer for a cold shoe, a one-half inch 1/4-20 bolt, flat washer, lock washer, spigot and this little Nikon L-bracket. I don’t know where the Nikon L-bracket came from because I shoot a Canon camera. All put together it puts the center of the flash much closer to the center of the umbrella.
