Suggestions? RotoPax mounting on the inside of a KB Voodoo rack

I'm new to the rotopax world and i'm trying to get my pax mounted on the inside of my KB Voodoo rack.

I'm using a double mount to try to get the can to clear the inside of the rails, but i'm running into an issue.

When I screw in to tighten, the mount doesn't go to 90 degrees, it's "off". Is this a function of not having the can mounted?

When I do have the can mounted, I cannot get the can tight. It wobbles.

So, I suspect that the double mount will not work.

Anyone out there mount their rotopax on the inside of a KB Voodoo rack and if so, how did you install the mounts?


thanks!
Dave
