I'll be installing an LCD television for my mother in her basement, and it's getting done on an exterior wall, in which the construction is 1/2 inch drywall backed by furring strips, then cement block. There's maybe a good inch between the drywall and the block. I plan to drill through the drywall, lined up with a furring strip, then into the cement block with a hammer drill and a 3/16 inch cement drill bit then using 1/4 inch x 2-3/4 inch long Tapcon anchors. I also understand that the cement block is hollow with maybe an inch or inch and a half of bite. My question to you guys is, will 2-3/4 inch length anchors be long enough? I plan to use 6 to 8 of them, 4 of which will be lined up with the two furring strips 16 inches apart for more snug of a hold.

The television is an LCD and weighs approximately 60 lbs. I plan to use a rack with the tilting feature, not the pivoting arm. TIA

think butterflies are better as addl length doesn't contact anchor block therefore useless,,, the main issue's pullout strength, not shear

Toogle bolts are a good bet. There is this epoxy type plug that works well. What type of block are we dealing with. Is it the red clay block. I would try to hit a mortar joint and place those plastic plugs with some screws as well. If it were my house i would cut back the drywall and mount a two by twelve to the wall first, I would also power grab it to the wall on top of all the toggles and rawls or what not. You will not see it behind the t v. It would also give you a place to mount an outlet and a strip to hold all the hdmi cables and what not.

If it were my house I'd build a second wall in front of the first, but only to the width of the flat screen maybe wider if you want to install some in-wall speakers. And you would be able to conceal all your wiring and add extra outlets and low voltage boxes for your speakers and cables.

Personally, I'd go with 2 - 3/8" expansion anchors at the furring strips as my first option, but the Tapcons should work fine as well.............

Thanks everyone. I'm going to give the Tapcom's a go, and if that doesn't work I'll try your other suggestions. Sounds like the butterflies wouldn't be that bad of an idea too, as long as I can find some long enough
