Width of the base: appr. 33.9mm (widest part of the dovetail part)
It means this is not a Vixen-style dovetail, so it won't necessarily work with all Vixen-style dovetail clamps.
It looks like the manufacturer attached a dovetail bar that is used by several manufacturers of photographic ball heads and video heads, so for example it is compatible with our PHOTO UNO and PHOT DUO Counterbalance Upgrade Kits.
We've also tried it with a Primaluce lab clamp, it is not compatible with it in a convetional way. I.e. the dovetail is too narrow, but the top part of the dovetial bar is wide enough, so the Primaluce clamp will hold it, however we would not recommend to use it that way as it might fall off if incorrectly used. (we won't take responsibility for a damaged camera...;o)
We've tried our own Universal Mounting Platform / Clamp and that holds the dovetail bar of this tube ring securely. As the same clamp is being used on our own Lightweight Aiming Platform, that is also compatible.
Otherwise there is a 1/4" photo thread at the base of the dovetail bar and another 1/4" photo thread at the top of the tube ring.
