/diy/ - Do It Yourself

Hi /diy/

I'm lifting a eight meters long 2x4 that's meant to stretch a projector screen for an art project. The ceiling is concrete, so I need to use expandable bolts, but it has a lowered section of ceiling boards that covers most of the surface. The 2x4 stretcher is getting mounted flush with the lowered section, so I can't used hooks to hang the structure, as it'll make a gap.

Pic related is the best I can come up with, and I'm thinking to secure each couple of eye bolts together with a couple of hose clamps - but there has to be a more elegant way to make sure the eye bolts are aligned, won't sag, and strong enough to lift approximately 22 kilos devided on five couples of bolts . Any clever ideas?
