Subaru 1-3-2-4 Premium join:2001-05-31 Greenwich, CT	Drilling into concrete ceiling I need to mount a projector that is about 12 lbs or so on a projector mount with a concrete ceiling, I was wondering what's the best way to anchor it?

Subaru 1-3-2-4 Premium join:2001-05-31 Greenwich, CT	reply to Subaru I have roybi bits it came in a clear case along with some metal bits, I have some tapcons but I just want to make sure it's solid since it's being mounted over a bed.

alkizmo join:2007-06-25 Pierrefonds, QC kudos:1	Projector on a concrete ceiling over a bed? Okay, Subaru, what is going on? Are you living in some sort of entertaining prison? Seriously though, Ryobi bits suck, but it might be able to get 4 holes. I think I know which clear case you're talking about. They don't have concrete bits in that box, only wood, metal and masonry. The tapcon box should have come with a bit. If you didn't use an oversized bit to drill the hole, your tapcons should hold pretty solidly. I'd only be worried about the concrete giving out. 12lbs is very little though. You'll most definitively need a hammer drill

Juggernaut Irreverent or irrelevant? Premium join:2006-09-05 Kelowna, BC kudos:2	reply to Jack_in_VA I was using a Bosch hammer drill, and the bits were pounded flat. I can relate. It wasn't 40' up though. That's ugly. -- I'm not anti-social, I just don't like stupid people.

Sc0tt Kneedragger Premium join:2000-11-13 Stockholm, NJ	reply to Subaru i have a hilti te-7c. it will drill into anything, including steel water pipes even when i did that, i didn't kill the bit. as for the 12 pound projector----the tapcons are rated for way more than that. i have also had good luck using redhead and hilti expanding anchors. they make small ones that should work if you go that route. they probably have better pull strength if it makes you more comfortable.

Subaru 1-3-2-4 Premium join:2001-05-31 Greenwich, CT	reply to alkizmo I want a larger screen size And for the ryobi bits I'm sure they are not great since it came with drill bits, screw bits and various drill sizes in a 30 pc case so you can only give so much for $16 or 20 I spent for it. My current hammer drill is broken from the fall 11 ft off a ladder, it still runs but I don't think loctite epoxy is enough with the forward force to keep the body from snapping again. -- It's NOT Ni-kon It's NE-KON!

Just curious - How does one avoid hitting a reinforcing rod? I'd hate to start drilling then be stymied by one of those. -- Buckle Up. It makes it harder for the aliens to suck you out of your car.

zach3 Zach Premium join:2000-05-04 Saint Louis, MO	reply to Subaru Here is another option. Why not clean the concrete ceiling and Ram-set a piece of 3/4" plywood with some PL 400 to the ceiling that is slightly larger than the footprint of the projector. Then paint or stain the plywood and use some wood screws to attach the projector. Just a thought.

PSWired join:2006-03-26 Annapolis, MD	reply to Subaru I find that drilling holes for tapcons almost requires a hammer drill so the hole size is accurate. Otherwise you're working at it so long that the hole becomes enlongated and the tapcon doesn't grip properly. Especially if drilling into softer materials like CMU.

Subaru 1-3-2-4 Premium join:2001-05-31 Greenwich, CT	Yeah I kinda figured this, the weight I listed before must of been the box and package but the projector alone is just only 6.6 lbs hardly much of anything.

Then paint or stain the plywood and use some wood screws to attach the projector. Because that would require you to ram set the plywood. Plus PL400. Then paint or stain it. Then secure it with 3/4" wood screws. All your work is to just to get to the same point you are at when you started...attaching the projector to something. Call me silly, but a couple of tapcons is going to be easier, faster, hold just as well. Plus little risk of spalling so when the time comes to take it down, you can and not leave a decent divit. Plus Tapcons can be installed by a standard drill if you had to. No Ramset to buy. Also no risk of the nail not driving fully and sticking out loose.
