Hanging a 55" LCD from cinderblock wall?

[Popeye the Sailor]

btw... mike says wood isn't dirty

To clarify a few things, yes, this is cinder block

wood and fake wood is filthy and cannot be used.

I don't know how they sealed the cinder blocks.

I need to prove I can do this without harming the structural integrity of the blocks.

So far, Nate's option seems best.

is the cinder block (cmu) hollow or filled?

[Popeye the Sailor]

Hollow.

Dear Dave,

If in hollow part of block use Togglers http://www.toggler.com/products/snaptoggle/overview.php

If in web of block or in mortar joints use double-expansion anchors http://www.confast.com/products/double-anchor.aspx or Tapcon screws

If damage is a big concern, (this is probably overkill) you can use a chemical anchor which doesn't apply any pressure to the block
something like: http://www.powers.com/product_8503SD_8558SD.html
with a threaded stud like: http://www.powers.com/product_6512.html
and if it's going into a hollow part use a screen tube like: http://www.powers.com/product_07967.html

Good Luck,
Mike

you could also use unistrut to spread out the load instead of wood.
You can get it at any electrical or mechanical wholesaler.

I'd just use the anchors like ducpainter posted on the 1st page. The wall mount bracket that comes with the TV should be sufficient for spreading the load, as that is its purpose. If it isn't, or you're not convinced after looking at it, then you could get something like this which will spread the load well enough.

Are you positive the cinder blocks are hollow?

I've mounted a lot things ( conduit, unistrut, shelves,...) on to hollow cinder block walls.

The expanding anchors are the way to go. Use a piece of unistrut as a spreader to distribute the load. I've had best results when I drill into the thick part of the block. The thin sections aren't as strong, try either 2" in from the edge or centered to catch the center web. Too close to the edge will cause a blow out, ask me how I learned that one.

The other possiblity is to drill all the thru, all-thread studs, and a metal plate on the back side. Don't think a TV is heavy enough to warrrant this.

I heard Billy Mays was working on a solution to this very problem when he met his untimely demise.

The Hilti toggle bolts are nice. Should work fine for a relatively light flatscreen.  If in doubt install an "oh shit" eye hook with a leash attached to the tv........just in case. 

Good luck!
