By the way, how do you guys determine the "perfect height" of the plasma?

That is an interesting question. I usually qualify the customer about their viewing habits and try to make it comfortable for them. I always try to avoid looking downward. I dont really get the fireplace location either but it their money and I want it.

The perfect height is often the one height it can be mounted at, especially if recessed. With other clients, I ask them and try to influence them not to put it too high or low if it looks to me like they are doing that.

With the Chief mount I did the other day, I screwed the mount to a piece of particle board, connected to a support to hold it upright on the floor, then hung the plasma to it.

I insisted on doing this because I have hung a plasma after installing the mount, only to find that there is some droop, so the vertical center of the wall plate was higher than that of the plasma.

I also call the manufacturer to find out if the mount's centers are supposed to be in line with the plasma's centers. What if the plasma hung 2" below center of a wallplate? That might be wonderful construction but you have to know about it before you drill into the brick!

Chief omitted a fact that would have helped A LOT: "The horizontal center of the mounting plate is XX inches to the left of such-and-such mark on the wall plate." It turned out to be about a half inch to the left of the right edge of the wall plate. The plasma had to be hung to measure this!

My distributor has the Peerless PLA1 plus adapter plate or the OmniMount UCL which includes the plate (cheaper). Does anyone have preferences on these? Are they both about the same depth?

Sanus tilt uni-bracket or a omni mount canterlever will do it. The sanus just needs 5/8 of an inch lift to drop down. The omni mount canterlever will need either 3/4 ply behind it to best center it because it is off center 71/2 inches. Also with the canti bracket you will need a omni mouny um1 which is a universal plasma mount.

Hey it s me again. Don't make this, this confusing. Center your main bracket by useing the differences around the plasma. then bolt it up.Good news it will cover any mistakes so try a couple of times if necessary. i just actually read some other answers and this is to easy to need all this hype. it should only take you about 30 minutes to figure it out. good luck.

I just used a OmniMount FP-CL on a Toshiba 26HL83 (46lbs) and could detect no sag at all. Seemed like a very well made item, so I would think that the UCL would more than likely be just as well made. I've used some of the other manufacturers products in the past (with reasonable success), but for me the OmniMount stuff just seems to be better engineered.

What do you do when you have to move a plasma an eighth of an inch up or down, the bracket only has horizontal slots, and you have just shoved anchors into holes in brick?

I guess I was being tweaky about the Chief not defining how the horizontal center of the front plate related to the center of the back plate. The horizontal slots on the back plate would allow plenty of adjustment if it initially went up wrong.
