Does anyone know where to get this wrench?

You might try McJunkin-Redman or some of the other industrial pipe & valve distributors.

Good luck ! If you can't locate one, I have a CNC plasma table in my fabricating shop & these aren't difficult at all to make - just need to know the LxW of the hole.

 

It's a modified valve handle. We carry a few in each truck in the event the site we are pulling from doesn't have handles (quite common hereabouts, at least on Chesapeake pads). I carry a large adjustable wrench in case of an odd size though.

 

Better than screwing up the camlock half of your 4/3 with pipewrench teeth...

 

Draw one up, send it over to Will and get him to fab 10 or so on first order.....start selling tools . Make your cash that way.....

Just sayin.....
