Edit: Buzzaw, if you missed it earlier in this thread, the pipe size you want is 1.25 inch (1 & 1/4"). Normally H.D. carries it in both "black" and galvanized steel. I opted for the rust resistant galvanized. I forget the length I got but it was threaded on both ends, and it was long enough to be cut into three 32" pieces (I may have gone with 31 inches?). They did have to cut 1 & 1/4" NPT Threads on 4 ends.
