The U-9 fits directly into the crossarm U-4 or UBA on the UST of UBA studio camera stands and has a 3/8" camera mount on a 90 degree angle platform.

The 3/8 screw mount is normally used for mounting a camera head, but you can use it to mount the appropriate computer accessory tray.

In beautiful condition as you can see in the image of the actual item.
