pole mounting and conduit questions [RE-wrenches]

[Nicholas Ponzio]

Does anyone have experience running conduit up through a pole? How do
you enter the pipe at the bottom? And do you run conduit all the way
up the pole or does the pole itself become your conduit?

We're using anchor bolts with a pre-welded plate on the bottom of the
steel pipe. See photo here:

What I'd like to do is run conduit up the inside of the pole and exit
through the "gimble" on the poletop. See an example of a light post
here: http://www.flickr.com/photos/14918878@N04/2214578212/
I haven't seen this done with PV but I'm sure it's possible. The DP&W
racks come with a knockout on the gimble, for this purpose. Not sure
about Zomeworks, though.

Any feedback is appreciated.

Thanks,
