I have a projector screen about 10 feet long and weighs 57lbs. My house is small and I have only one location where I can put it and have enough space for a projector to throw an image. In that room the walls have paneling which I don't think I can drill into and later cover. So I'm left with installing into the ceiling. There are no joists in the area except for the joists which are covered by beams across the ceiling. I can't drill into those either without causing them damage. So now I'm left with trying to install this thing into a drywall ceiling without a joist to drill into. Also that part of the attic is blocked off by the heating system and vents...
It's a frustrating problem. Can I get away with toggle bolts?Any other ideas?

 

The paneling or beam are your best bet. Any holes in wood can EASILY be repaired. Don't think you can hang it from drywall with toggles alone. If you were to attach it to the ceiling drywall, you would need to glue (construction adhesive) and toggle a 2x4 to the ceiling drywall first.

 

You certainly can mount that into the ceiling joists. We do it all the time. 57 pounds is not that heavy. Even better if you're picking up several joists.
