If your not use to doimg installs its best to call a professional. I have been putting these up for quite some time and this model has been the most difficult. Doesnt come with a level like the other 20 dollar wall mount, wayy too many extra pieces, and the bolts, screws and other metal pieces strip way too easily. Tried to follow inatructions and install to tv before mounting it up on the wall and almost destroyed the wall so i took it apart. Installed the mount to the wall then had my fiancee hold the tv up so i could attach the back to the mount. Was way easier done that way. Just get the other brand. Its more expencive but its worth it. This brand is a big headache. You have to pre loosen the joints as well for a good motional range because its waaayyy too tight.
