Abstract
A device for supporting a circular disc to be cemented in an opening in a rigid plate-like member, such as a pane of plate glass, comprises a support frame, a first set of legs around the perimeter of said frame, and a second set of legs spaced inwardly from said first set of legs. All of said legs are terminated along the same plane spaced from the frame member. A support element has a suction cup to hold a rigid plug having a diameter less than the area circumscribed by the first legs, and greater than the area circumscribed by the second legs. A spring resiliently urges the plug against the ends of the second legs so that a surface of the plug lies in said plane. The frame is held against the pane or plate like member so that one surface of the plate member also lies in said plane and the plug can be held in the hole with one surface exactly parallel in a plane coincident with the plane of the plate.
