When I saw them, all I could think "you always need more clamps"
Besides. their a cool tool, and everyone knows you need more cool tools.
The one thing they will be good for, is stabilizing the center of cauls. They could be applied to prevent any unwanted potential bowing in the center
I have 2 big ones like that they were in a group I bought heavy as crap no idea what I would use them for lol
