A:
The set up is actually quite simple and very secure. Once you figure out part B uses screw EE LOL it goes together very well. The 2 vertical bars mount to the back of the TV with the large rectangular bracket mounting to the wall. Must be screwed in to 2 studs to support the weight. Once the 2 components are mounted securely then the TV just hangs on the wall bracket and it click locks into place for a secure mount. I'm very pleased with how it handles my 70" TV.
