I just saw a photo of a corporate event with a bunch of truss in the sky.
Apparently, the points in the ceiling were in 2 lines, left to right.
They needed to fly 3 VERY LARGE projectors that wouldn't fall on those lines.
The crew rigged a line of truss along each line of points; so there were 2 parallel lines of truss 30' apart.
Then, they used ratchet straps to connect perpendicular sections of truss to the flown sections, and hung the projectors from these.
I've seen a lot of different ratchet straps, with various types of hooks on the ends, but I've never considered using them for overhead work.
