A question that doesn't seem to have been raised is whether this is a good material for HF grounding.  I just verified my memory that W8JI questioned that, because of the multiple fine wire construction of the braid and the consequent likely increase in resistance as thebraid aged.

FWIW, I use 3/4" copper pipe run along the back edge of my operating desk, with silver soldered joints.  Individual pieces of gear are connected to it with #2 wire, ring terminals, and internal toothed lock washers to ensure good connections.

"Kurt, you are way off base talking about auto parts stores the way you have. You have obviously made an assumption. Trust me, I owned an auto parts store for over 20 years and we, meaning my store and my suppliers had a large variety of connectors and lugs from the same suppliers as any other hardware or electric supply house."

No, that's forty-one years of experience as recent as last December.  You had a store, you know what I'm talking about, you don't need to try and convince me of anything.

I suggest those wanting higher quality components, even just connectors and terminals, search military, aerospace, and medical suppliers for traceable products- used in applications that matter, where failure is very bad, so by design and application, unlikely to ever happen.
