A mounting system for releasably securing an object to a walled surface is described. The system comprises at least one magnetic element; a magnetic counterpart coupled to the object and configured to magnetically engage with the at least one magnetic element; and a mounting plate having attachment means for securing the plate to the walled surface. The mounting plate comprises an exterior surface for releasably securing the object thereto; an interior surface for securing to the walled surface; an indentation in the exterior surface for receiving the counterpart; and one or more recesses in the interior surface, said recesses contained at least partially within the boundary of the indentation on the exterior surface. The at least one magnetic elements are located within the recesses and the counterpart is coupled to the object to magnetically attach the object flush to the mounting plate when the counterpart is received in the indentation.
