Thanks for the post. Being 6'2" and having an 8' ceiling, I want to maximize height where possible. Given that the hardware increases the distance a few inches, I may mount a smaller 2X6 above either flange (instead of a single piece), saving the 2" for headroom there and giving it right back by using 10" nipples. When space is so tight, every inch or two counts. Thanks for the advice, will post pictures when complete.
