The hot shoe adapter consists of a metal plate with approximately 1.5mm thickness, is square with rounded corners and a respective edge length of about 1.8 cm.
In my case, the flash bracket so upper hotshoe receiving area is not as shown here, flat and lower portion narrower and higher (in the picture there is the hot shoe adapter screwed), but both are hot shoe receiving area equal and correspond to the flat top portion.
The inside width of the receiving region of the flash bracket is 1.9cm. Here one should be careful so that the existing hot shoe adapter Speedlight / microphone / video light can also be fitted according to the intended direction!
For me it was so that for example a microphone (Takstar SGC-598) would only fit if I had turned about 90 degrees inserted it into the flash bracket, since the hot shoe adapter of the microphone while fits in width, but narrower in the longitudinal direction is. The course would have been stupid, because then "watched" the microphone to the side, but not to where the camera is looking. Fortunately, makes the hot shoe of my mics solve with a screw and rotate according to 90degrees.
So rather remeasure again, otherwise you may still need an extra adapter.
