Gentlemen:
I have the Rohn BPC25G, which is the concrete base plate for 25G. It
requires a single pier pin, but there are two holes - one in the center, and
one at the edge of the plate. I realize I use the center pin, but what
purpose does the other hole serve?
The pier pin, Rohn 3/4x12PP, is also a smooth pin, without any other
features. There is nothing to hold it in the concrete.
Would 3/4" threaded rod (material is similar to the pier pin), with large
fender washers also serve as a better pin - at least there would be
something to hold it in the concrete. There is nothing that I have found in
the Rohn catalog that would provide me guidance.
I would appreciate your guidance.
Scott
