I’m looking to install a projector in my basement and the most ideal configuration would be to mount it to the ceiling with a ceiling mount. However, the “sweet spot” location for hanging (in considering distance to the projector screen) falls underneath a bulkhead that houses AC and heating ductwork, and I don’t detect any beams with my stud finder.

I obviously don’t want to mount directly into the ductwork for many reasons (vibration, projector misalignment due to changing temperatures expanding/contracting, air leaks, etc.).

What are some other options? The projector is only 8 lbs., so can I use construction adhesive (like liquid nails) to adhere a piece of wood onto the drywall, and then mount the projector into the wood? The projector mount includes 2.5” lag bolts for mounting...

I’ve also considered a projector shelf on the back wall but given the distance to the screen, the projector lens should be 28.24” from the back wall - so that would be a very deep (and perhaps custom built) shelf.

Here’s a picture of the area. Thanks!

    The drywall of the bulkhead has to be screwed in to something. There is framing in there. Instead of a stud locator, try a strong magnet to locate the drywall screws. Dec 23, 2020 at 16:41
  • The zoom should be able to handle a measly extra foot of throw. Get it atop a bookcase or something before you decide to start drilling holes. Ideally you set it low so you don't have to keystone the crap out of it.

There should be some sort of framing around the ductwork although I would bet it's just a 1x2 board and not suitable for lag bolts.

I would suggest to do the shelf idea or mount it from the ceiling.

    Thanks. I think I'll have to go with the shelf option as the real ceiling is too far forward.
