ABSTRACT:
A screw anchoring device for aperture sealing attachment with an apertured panel to confine insulating material foamed in place between the panel and an attached spaced wall or other structure. The device includes a plate member having corners and a generally flat portion lying in a plane with a central aperture forming a helical screw receiving impression. The device also has a pair of upstanding tabs projecting from one face of the generally flat portion of the plate member at opposite sides of and adjacent to the screw impression. The plate member has a raised portion formed from the plate member at the corners and along each of two opposite edges of the flat portion of the plate member. These raised portions are convexly curved upwardly from the plane of the flat portion and from the face opposite from the face with the upstanding tabs and the corners of the plate member are semi-spherical shaped. There is a continuous pad of material capable of being penetrated by a screw and having an exposable adhesive surface substantially covering and carried by the plate member with the tabs projecting for entry into the paneled aperture and through the pad and having the adhesive surface of the pad extending across the panel aperture for mounting and sealing adherence to the adjacent panel surface to prevent egress of trapped insulating material through the paneled aperture. The screw impression is in position for threaded engagement with a screw passed through the panel aperture and the pad for attachment of a utility component to the opposite panel surface.
