Abstract: There is disclosed a universal mounting bracket for the removable attachment of a radio and the like to a support structure such as the dash or interior wall surfaces of a vehicle. The bracket comprises a base member with tab supports to secure the base member to a supporting structure. The base member bears a longitudinal, coextensive lip along one edge and bears a plate member slidably carried thereon. The plate member bears a second lip parallel to and coextensive with the first lip. The bracket also includes a resilient spring biasing the plate member towards the lip of the base member whereby the mounting bar of a radio can be resiliently restrained between the opposed lips of the bracket. The bracket is assembled by fasteners which permit the fixed adjustability of the spacing between the opposed lips whereby the bracket can be adapted to fit a multitude of radio units of varied dimensions.
