Abstract
Apparatus for sealing a postage meter is disclosed. The sealing apparatus includes a member with a cut-out portion. The cut-out portion includes two cover tab receiving openings which are positioned diametrically across from each other. The center of the cut-out portion has a bore hole that runs completely through the thickness of the cover. An insert is provided with is adapted to fit into and mate with the bore hole. The insert contains an opening which will accept a screw and also contains upwardly extending tabs. A screw is used to fasten the sealing apparatus to the postage meter. A cover is stacked over the upwardly extending tab of the insert. The cover is welded to the upwardly extending tabs thereby making it impossible to remove the screw without first drilling a hole in cover and thereafter prying the cover off to expose the screw. A broken or fraudulent cover will indicate that the meter has been tampered with.
