O with the line through it is a geometric dimensioning and tolerancing symbol. Means Diameter.
I need to take another look at that drawing. The pipe actually hangs off the ends by a couple of inches on each end now and that diameter should be 1.66” (but that is before galvanizing).

I'm assume that's outside diameter, is that right? Josh Luthman Office: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373
