Suspending a projector from ceiling...fixings?

[GinG]

Hi All,

Quick question, total weight will be around 4.5kg and wanting to suspend the projector from a ceiling which is just plasterboarding.

Will I be ok just using the spiral plasterboard fittings? Have used in the past with good results on mounting TV's just wondering if ok for the ceiling?

4 will be used to secure in place.

Thanks

I wouldn't risk it. I'd look for some medium to heavy duty cabinet fixings and use those instead.

Could you possibly link to what you are suggesting please?

can't you position the mounting plate over a joist so you can screw into wood for at least 1-2 holes?

Something along those lines.

It MAY be an option, just waiting for the projector to arrive, however due to the location and spacing of the joists it may be the projector is too far forward and a little more obtrusive in the room.

Another option is I do have some 5x1 down the side of house. An option is to cut to length, get some 90 degree angle brackets, screw into the wood and joists, however need to get up into the loft again to see if this is an option.

Thanks, used some for the wall mounting in our bedroom actually.

Once the projector arrives will have a nip to the shop and see what options I have. Only problem with them toggle ones is the required drill size bit. I had to borrow a mates SDS drill but he is now away.

That's what I've done in the past when putting up friends Projectors. Would be my preferred option.

Just use the biggest drill bit you have and wiggle it about as you drill to widen the hole as appropriate.

I'd go for the joists for this one, myself, though.

Great, thanks for all your help guys.

Just waiting for the arrival of projector to make sure the mount fits before I start poking holes in the ceiling!

I would definitely go down this route. I helped a mate fit his a few years back in his living room and we cut a section of ceiling out and ran some 2x4 between the joists and then fixed into that. Bit more work but its not going to a) pull your ceiling down and/or b) kill someone!

3M command tape should do it (maybe not) but they claim to hold 1kg per set, so in theory 5 sets = 5kg max weight

I have always used spring toggles as per the screwfix link above. Very strong, you'd rip the section of ceiling out before they come out. Either that or just try and go into a joist if convenient.

That sounds like a terrible idea.

You don't need baton / giant brackets / going into joists etc.

Anyone suggesting so is wasting time and money.

Just use spring toggles, as has already been said.

indeed, hence the "maybe not" part of my post.

Will get some photos tomorrow, decided to use a bit of 4x2 cut to 570mm and fitted it between the joists.

Used some screws and washers to gold the bracket in place and it is very very stable. Definitely not going anywhere any time soon!

Thanks for your help guys.

Please. Also got the same job to do, just need to fine tune the final location.

The problem with this, is if you want the cables to go up the middle of the mount, they would have to go through the joist too...

Not really, plasterboard fixings are all intended for vertical loads - clamping something against the wall and then relying on the rigidity of the wall to hold them up

as soon as you apply a forward stress to this fixing (as in a projector hanging from a horizontal board), then you are merely relying on a 2cm patch of plaster not giving way.

In this case maybe it would work, but its wrong to dismiss any fixing as adequate when it is used outside of its normal intended use and the loadings are entirely different.

Say if a mounting pole was being used, that has the same overall weight but the loading is now completely different due to possible lateral loads and the fixings could then easily fail

Looks like I should have read the whole thread
