ABSTRACT:
A retainer for securing and retaining a pre-hung door unit in a closed position relative to a door jamb. The retainer includes a shaped cylindrical plug configured to fit closely in the edge bore of the door. The plug is insertable into the edge bore through the face bore of the door and has lobes extending transversely to limit its entry into the edge bore. The placement of the transverse lobes maximizes the length of the plug extending from the lobes which enables an end of the plug to extend beyond the door edge into a bore in the strike jamb of the door jamb when the door is closed relative to the door jamb. A bolt extended through the back of the strike jamb and engaging the plug secures the plug in position and secures the door in a closed position relative to the door jamb. The bolt may be tightened adequately to clamp the strike jamb to the door edge. The bolt and the plug are provided with double lead blunt end threads for rapid assembly and disassembly. The plug has relieved sides for ease of moving the plug within the edge bore of the door which is a benefit for installing the plug and also is an aid to a door installer. A cinch ring provided on the plug near the extended lobes prevents lateral movement of the plug in the edge bore. The configuration of the plug accommodates both circular and rectangular bores that are normally provided in the strike jamb of the door jamb.
