Hi Roger,

The holes in my pole are right at under 3.3/8" below the welded seam, with the holes drilled in the "valleys" of the corrugated pipe. I would drill a hole in one of the valleys, line up the hole with the data plate (the ends of the tag will have to be bent to fit the corrugated pipe), and then mark and drill the other hole. The tag should be centered above the bottom wiring access hole.
