I am in a dorm room and I am attempting to mount my projector and screen in my ceiling... As far as I can tell from just tapping the ceiling it is made of cinderblocks if that sounds right or something similarly tough.

I have absolutely no idea how to mount the projector and screen in the ceiling and would appreciate any help...

What tools would I use? Since I don't own anything but a hammer and screw driver, would I be able to rent the tools? If so, where?

    Better check with the school before drilling holes is their ceilings.

    Thankfully, the school does not care :) I checked before I even bought the projector!

  • How heavy is the projector, and how many screw holes are in its mounting bracket? This will help determine the type & size of anchor you'll need to use. Jun 1, 2012 at 17:42

Berkeley, CA has a tool library for just this kind of rental. Major home stores have rentals, and there are chains of rental shops like Hertz Rentals.

You'll need a drill, a masonry bit, and a concrete anchor. Your local hardware store can supply the last two. Each anchor will have a specified hole size.

The ceiling is almost certainly not cinderblock. But it could be reinforced concrete, which is a good strong material to anchor to.

    You'll want a hammer drill for this..

    A rotary drill works just fine for small holes. A pro would insist on something faster, but as long as you can go slowly (1-2 minutes per hole) rotary is good enough, and far easier to find.
