I live in a loft space with exposed beams ~9ft apart and vaulted ceilings. I'm trying to cordon off part of the space with a divider curtain. I previously tried a tension rod which sagged too much due to the span length, so now I'm trying to figure out how to mount some sort of pipe between the beams that I can then put a curtain with 1.5" diameter grommets on. After many hours of combing the hardware store, I still can't find something that seems like it will solve my issue.
Floor flanges for pipe that I can find all seem to be threaded, so even if I could cut a pipe to the exact length between the beams, I would be losing the threading and thus unable to attach them on one end. I can't find any other option that would allow me to just go straight across between the beams (I'm all ears if there is one as this seems the ideal way to do it!), so my other option would be the ceiling. From the ceiling I need to come down around 12-14 inches to clear an exposed sprinkler pipe.
There are two issues I'm having here. While the thinner (~3") pieces of wood that run perpendicular to the beams might just barely be wide enough to attach a floor flange, two pieces of pipe and two elbows for a U shape, all except the very last one closest to the wall are at an angle due to the vaulted ceilings. Additionally, were I to go this route, I'm not sure what I need screw-wise to ensure the weight is accounted for. I used lag screws with a hex head for a projector mount once, but I'm not sure how long these ought to be and lag screws don't seem to be the correct width for the flange holes regardless.
The other option that appears to have been used for the existing sprinkler pipe seems to be sinking some sort of hex shaped sleeve with a threaded inside into the wood (no idea what this is called). Into that sleeve a long bolt comes down and on the end is a clamp with short bolts on each side that allow the bottom to come off so the pipe can be sandwiched between that and the part attached the the bolt. This would probably work except that I can't figure out what any of these pieces are, especially the thing that goes into the wood.
After stubbornly spending most of the day trying to accomplish what I initially thought would be a very straightforward task, I'm hoping someone can suggest a solution either by suggesting something I haven't thought of, or identifying the pieces I can't figure out since I'm presently pretty frustrated and stumped.
