I'm all about visuals, and understanding things by seeing them... but...
uh... what is this for?
I'm actually quite lost on this one it seems.
Edit: Ok. Seeing this pic helped me see what it was going to be used for.

There is only one issue I can think of right now. When you move the bolt so the head is sticking out of the frame more to increase(?)/decrease(?) tension as it may be, wont that bolt go out of profile if your frame is not short enough to account for that? (Edit: Wait... will the bolt head move, or is it just acting like a lead screw?
<-- Answered below by Nuttyman. Thanks. I was imagining something a little different than how it actually works.)
It is a cool concept.
But, I would have rather used a turnbuckle style fastener between the centers of the pillow blocks rather than something on the outside if that would be possible while not interfering with the chain itself running (presumably) inside the box extrusion.
Also, a side question for teams who run chain inside box extrusion.
Have you ever had problems of your chassis getting damaged and thus the deformed shape interfering with the chain running inside?
