This may require some drilling and/or use of a level. Use rubber gloves and safety glasses when installing your TV to protect yourself from injuries that could occur if you accidentally touch exposed wiring or drill into the wrong surface. Also, never attempt to install a TV without help, especially when using tall ladders. If something were to go wrong, you would be stuck in an extremely dangerous situation with no way to get down safely unless someone helped you out.
After mounting all the components, use screws and other fastening devices instead of nails or tape to secure it more securely in place so it can bear its weight as well as that of wiring attached behind it or any items hung underneath it.
