I'm planning on mounting or hanging a truss between two beams in an older theater. (They currently have gas pipes across the beams for basic par can hanging, but of course they wouldn't be suitable for intelligent fixtures). The only thing in my way is this unistrut. Here are the options I can think of. I plan on hanging 5 Rouge R2 Spots across the 20 foot span. Each fixture will weigh around 50lbs. Do I need a 12"x12" truss? Or is there an easier solution? (Double rail?) 1: Cut the unistrut, slide the trust between the beam and ceiling like I was originally planning on. 2: Use a sling to hang the truss off of the unistrut, but my concern here is can the unistrut take that weight. Anyone have other ideas? There aren't any higher beams to use a clamp, chain hoist, and spanset on. Thanks!
