An improved electrical box extension can be used to easily and securely mount an electrical device, such as a switch or electric outlet, flush with a new surface installed over an existing surface, using an existing electrical box which is fixed within the existing surface. The electrical box extension comprises a generally tubular body sized to receive an electrical device, and to be received within an existing electrical box. The body has flanges extending outwardly, and depth adjustment screws extend between the flanges and attachment bars mounting the electrical box extension on the existing electrical box. The body and adjustment screws can be used with an electrical box having integral attachment bars.
