I am going to mount a flat screen on a rock fireplace. Some of the rocks extend 2.5 inches from the concrete. I plan to mount plywood first, then the bracket. Any ideas on mounting the plywood on a very uneven surface? thanks, joe

last time I had to deal with a rock fireplace (are any of them a level surface?) we mounted the bracket to the fireplace using togglers and used spacers to push the arms as far away from the TV as possible.
I forget what size it is, I think it was a 65". anyway here is a picture of it

Long lag bolts into whatever is most secure (stone or studs if it's a stone veneer) and then varying amount of washers on each bolt to level the mounting bracket evenly.

Either use washers or 1/2 nipples or 1/2 threaded pipe cut to size.

Or all-thread with nuts adjusted to stand off, with washers .

I just cut off peices of conduit at the lenght I want to use as spacers for the lags and paint them black. Always works for me.

I was going to say shims and a chisel for stones that stick out exceedingly far,

But I like this idea Bruce, what are you using to attach the all thread to the stone?

Just did one last week and used large flat washers behind each lag bolt.


Had to chisel out one of the stones so I could run the electrical and cabling first, which allowed for determining what was behind the stone. Lucky for me this one was plywood, but I have seen the stone (both real and faux) on OSB and sheetrock.


I've used metal pipe to sleeve the lags, but using washers seems to work equally well if not better.


Hint: Measure for the stack of washers, stack them up and then use some tape to hold them together to make it easier to put them into position. Remove tape after they're in position and do some paint touch up if they show at all.

I have used these:

and a couple of nuts and washers. You can have the bracket far from the wall or close, just move the pair of nuts and washers up and down the threads. Really works well, and rock solid. Just make sure that you have it all figured out when you put the bolts in, there is no way to remove the bolt from the hole once it is in.
