Projector in the ceiling - Plug?

[blankner]

I'm about to set up my projector, Sony VPL-HW50ES, on the ceiling (concrete) with a mount from the brand Chief KITPD003 http://www.prisjakt.nu/produkt.php?p=493049Chief KITPD003.

The mount has four holes to attach to the ceiling. The projector weighs about 10 kg.

My question is what kind of plug and screw I need. Is a plug with nylon about four-five cm long sufficient or do I need something more robust?

I've heard about Fischer's SX-10 plug, is it reasonable?

I've never mounted anything on the ceiling of this weight class.

Maybe expansion bolt if you are concerned.

For example, http://www.biltema.se/sv/Bygg/Fastelement/Skruv-och-Bult/El-och-Blankforsinkat/Expanderbult-19920/

You want the mount to hold firmly, so the projector doesn't move just because you accidentally nudge it a little.

Concrete screw.

Concrete screws make sense. I read a bit about it, it seems like you don't need to pre-drill or have plugs? Is that correct?

 

[Stefan N]

Predrilling is necessary, but no plug.

I'll go with that! Thank you Stefan for the help.
