The screen brackets have several slotted (adjustable) holes. These allow the bracket to slide an average of 1-1/4 inches when the machine bolts are threaded into the back of the screen. The bracket kit is provided with several machine bolt sizes which should cover most brands of screens.
Provided your wall space allows for proper installation procedures and you can support the wall bracket with at least 16-inches of separation between support screws, you should be fine using the bracket.
