I had an idea and thus far, it works well enough and it was incredibly simple to make, but I'd be interested to here any comments or criticisms about doing this. I cut the 3/4 conduit as close to flush as I could get them and anchored them together in a kind of sled as pictured. Currently, all of the weight hangs from one end but it could be moved to the center of the pieces that run parallel to the i-beams which would help spread the load out more, but that's not necessary at the moment.

I wanted to suspend this from the I-beams in my unfinished basement to hold a couple workout bench seat pieces when they are not in use. It's a small load (less than 100lbs with everything on it) and I'm fairly certain there's never going to be much lateral force applied unless something falls into it. I'll likely add some horizontal bracing between the adjacent I-beams just to be over cautious.
