    Interesting the original ceilign will have some beam above the plaster work somewhere for you to get a fix into so the unistrut solution could work, batten down with timber from the orignial and then use the plates (or decent plywood) around the I beam and fix to that. Where there is a will there is a way

    You can also use Beam Clamps around the edge of the existing beam if you don't need to move the projector too far from it, they clamp onto the edge of the beam and use the uni-strut fed through it to make a tight fix, they work well I have a few items up that way

    chazzy2501: We can't hang it directly from the beam because the grid structure is directly below annoyingly. I'm not sure if there's a right angle mount? We've not had any luck finding one so far, but the beam is a bit small so won't take a large connector.

    Get some unistrut and some beam clamps to give you a fixing to the side of the beam location and then mount projector mount to the unistrut.

    john: it looks like a reinforced concrete ceiling with the metal formwork still in place below. Difficult to drill into I suspect, and may even require a diamond drill if it's very tough cement.

    plexer: D&T room. Apparently they used this beam and another further down the room to suspend a plane wing while they were working on it (!). The teacher discovered them, hung off them, and decided they were strong enough

    Unistrut sounds like the thing. I'll get a picture if it still proves to be complex! Thanks all for the suggestions.
