An improved apparatus incorporated in a cast metal frame of circular configuration to allow one frame to accommodate similar objects of slightly different sizes and retain them therein to prevent rotation of the object within the cast frame. Further improvements are designed in the retaining means which rigidly hold the object in cast frames of circular, rectangular and oval configurations while at the same time allowing the retaining means to be easily removed.
