Conestoga Wrench

I've been running Power Only loads with my own authority lately (pretty much sucks btw). But, I've seen a few Conestoga loads recently and they always note that I need my wrench? What is a Conestoga wrench? I've never heard of it before.. obviously never pulled a Conestoga either but I wouldn't mind giving it a shot.

TIA

 

So, its not universal at all? What wrench you need depends on what tarp system they have? Sounds about right..lol

 

Thanks. I asked on a FB group as well.

Im thinking I need a 3/4 break over bar with a 1-1/4 socket and then a 3/8 hex tool fit the same 3/4 break over

Would those 2 cover everything out there?
