A flush-mounting system includes a mounting bracket with an opening that is coupled to a support extending substantially in a plane to allow the mounting bracket to move along the support. An inner bracket is disposed with the mounting bracket's opening and can be slide in and out of the opening to adjust accordingly. Among the many different possibilities, the flush mounting system also has a second support extending parallel to the first support and a mechanism coupling an opposite side of the bracket to the second support. It is further contemplated that the structure is a stud of any structure in a building such as wood, cement, masonry, and stone. A wallboard is then provided to cover the mounting system for a flush-mounting look.
