Let's not get too tied up in listing. If it is a bronze acorn, the right size and made up properly it is OK by me. The next connection in this Ufer system can be a regular old rusty snap tie. It is the metal and concrete matrix that makes up the electrode.
Since the areas I have worked in did not make the connection to the grounded conductor in the meter enclosure I always asked to have a piece of galvanized rebar stubbed up out of the footer just inside the foundation wall if the block crew was not the same folks as the concrete crew and at the top of the basement wall inside of the sill plate if it was a poured foundation. I caught two different block crews sticking a scrap of rebar into the top of the block rather than lift the block over the stubbed up rebar. I guess their not allowed to cut out the end web of the block to make positioning it easier. -- Tom H
