Curious how to go about this. I need to install an outlet in a stone fireplace for an LCD mount... I don’t think its real stone, rather synthetic if it makes any difference. I'm not sure what to use to get a nice cut for the box. Any help is appreciated.

You will need a good hammerdrill (perferably a corded one). A 1/4" masonary bit. A 4" angle grinder and some cold chisels. A face mask and a vacuum would also be good.

I am just curious, how will you get the wire to it?

how do you get the wires to it?

What is behind the stone?

Theres drywall on both sides, Im ging to put inwall speakers on either side which will give me access to pull the wires......i hope. I'm pretty sure it hollow behind it. Do I drill first then use the grinder to square it up?

low profile surface mount box

can you give me a manufacturer or are the as common as reg boxes? Thats a good idea.

How old is this? I mean, if it were in California (your profile doesn't say where you are, which would allow suggestions from people in your region) and maybe as much as ten years old, you could count on it being a double metal tube with air space around it. Fifty years old, it's probably solid brick behind the stone. In between. anybody?

And how do you get the signal to it?

I hate to be the a$$hole here, but if you have to ask, you don't know what you're doing. Where in the country are you?

I’m in Kennett sq Pa. Sorry I didn't have that in there. I work for a co. that specializes in custom home theater systems, mostly projection sys. this is the first time someone has asked me to put an lcd over a fire place. It’s a brand new house. The fireplace is on an exterior wall, huge cathedral ceiling,(stone goes from floor to ceiling). The gas is vented very low, which leads me to believe (and I talked to some people who install the fireplaces) that the portion behind where the TV is going to be mounted is an empty cavity. There is a bump out for the vent on the outside wall and for esthetics they continue the bump out all the way up to the 2nd story. There’s no vents etc... out the top. I'm only running an outlet and or HDMI or Component cables to the back of the TV along with electric. The receiver controls everything else. Just thought someone could tell me how to cut a nice outlet box. I'm not completely out of my realm here, just wanted some input.

If the outside of the chimney is vinyl siding, it's a good bet it's not solid brick. Also a good bet there are studs behind the stone to mount to too.

personally I have the stone guys come back and cut the hole. That way if it gets screwed up they are right there to fix it. They can get that hole in there in half the time it will take you.

1) How to tell if it is hollow- drill 1/4 inch hole near where your speakers will be cut out. Then use your fish rods to poke around.

2) Push the rods toward the back of the mount and see how free your wires will be behind the synthetic looking brick.

3)Think good thoughts.

cut the drywall holes first for the speakers. That way if its not hollow you dont have a nice hole in the stone.

hire a pro....
