Abstract: The mounting apparatus is used for securing an electrical device and its electrical outlet in place over the original outlet box in a wall which is to have siding applied thereto. The mounting apparatus comprises a first plate adapted to be secured flat to the wall to be sided and positioned over an electrical outlet box therein. The first plate has an opening and a rectangular wall surrounding the opening and rising from its top surface. A second plate is provided having an opening and rectangular wall means surrounding the opening therein and secured to its lower surface. The second plate is coupled to the first plate by means of the two walls on the plates being adapted to form a tight mechanical fit with each other.The openings in the two plates are aligned with each other and this permits the electrical outlet to be removed from the outlet box, drawn through the aligned openings and secured to the second plate.
