Anyone make a ratcheting wrench for a cat 1 top link?

[Shawn T. W.]

I’m not sure how any of this would work with my jam nut as I need the nut to keep my link from turning.

What if you could just put a bungee on one side of the wheel (through a spoke or hole) and hold it so it can't turn?

If the wheel is stationary, and both ends are pinned, it should stay in adjustment ...
