We have not made them available for years. This one looks close, but not quite the same.

We modified them with a larger nylon washer and a copper washer under that to properly clamp on the chassis panel. They look cool, and grab large bare wire well. OK but not great with banana plugs and rather difficult to clamp onto spades. When the price nearly doubled a few years back we tried some similar looking ones (similar to those shown at PE) but they were not the same physically, nor of the the same level of finish. So we went to the more typical posts that everyone uses.
