If you use SB900s, like I do, then you may wonder how to attach them to some accessories since the flash’s larger hot shoe plate won’t fit a standard TTL cold shoe mount. One item we use frequently are Manfrotto Justin Clamps, they are very handy to attach SB900s in a variety of situations. The SB900 will not attach to the cold shoe mount that comes with the Justin Clamp, but there is an easy fix. I unscrew the plastic cold shoe mount and replace it with a Stroboframe flash mount adapter.
To attach the Stroboframe bracket, use a 1/4″ x 3/4″ set screw socket. These screws can be found at any hardware store. Just screw the socket into the clamp, and then screw the Stroboframe bracket onto this. You’re ready to go!
