Comments about Apogee Apogee 32-50" Corner Tilt Swivel Arm Wall Mount Bracket HDTV Plasma LCD VESA 600X400:
Instructions are not exactly clear, but I had the TV on the wall with no help in about 2 hours. You better figure out the angle ahead of time, its a cast iron &!T(# to get it set when the TV is on the mount! Sadly, I ended up cross threading the screw that sets the angle, so it will permanantly be at the current angle. The only way I'll be able to change it is to use a bolt/nut instead of just a screw in the threads.
But, its a good price, seems to be fairly sturdy, I just hope it doesn't come crashing down at some point taking my TV with it. I may add a safety strap, though with it mounted from the wall the swing down would probably still take out the TV.
