Shipping retainer for prehung doors

Abstract

A bushing for use with a door plug for securing a door to a metal frame. Said door prepped to receive the door plug with the door plug extended from an edge bore of the door and extended through a striker prep opening of said metal door frame. Said striker prep opening oversized for the extended end of said door plug. Said bushing configured to have a protrusion exterior mated to the striker prep opening and a through bore mated to the extended end of said door plug. Said bushing inserted into the striker plate opening and said door plug end extended through the through bore of said bushing whereby a fastener secured to the extended end of the door plug secures the door to the metal frame.

1 . A bushing for use with a door plug for securing a door to a metal frame, said door including a face bore and edge bore and said frame including a configured striker prep opening that is oversized for the door plug, said door plug extending from the face bore into and through the edge bore and through the striker prep opening, said bushing comprising: 
 a body portion defining a through bore extended through said body portion from a front side to a second side of said body portion, and including a configured protrusion on at least one side, said configured protrusion mated to said striker prep opening for insertion into said striker prep opening and as inserted for securing the bushing against lateral movement of said bushing relative to said striker prep opening;    said through bore configured to receive the door plug as extended through the striker prep opening to secure the door plug against lateral movement whereby a retaining fastener on said door plug can be secured to the extension of said door plug to secure the frame to the door.    
   
   
       2 . The bushing as defined in  claim 1  wherein said configured protrusion and said through bore are in side-to-side offset relation and with the protrusion inserted into the striker prep opening provides a first position for said through bore and with the protrusion rotated 180° and inserted into the striker prep opening provides a second position for said through bore, said first and second positions accommodating different door thicknesses wherein the edge bore is centered in the door thickness.  
   
   
       3 . A bushing as defined in  claim 1  wherein the bushing is designed to accommodate a second metal frame type having a different configured striker prep opening, said bushing comprising: 
 a second configured protrusion on the opposing side of said body portion and mated to said striker prep opening of said second metal frame for insertion into said second striker prep opening and as inserted for securing the bushing against lateral movement of said bushing relative to said striker prep opening of said second metal frame, whereby the retaining fastener for said door plug can be secured to the extension of said door plug to secure the frame to the door.    
   
   
       4 . A bushing as defined in  claim 3  wherein said second configured protrusion and said through bore are in side-to-side offset relation and with the second protrusion inserted into the striker prep opening providing a first and second position for said through bore and with the protrusion rotated 180° and inserted into the striker prep opening of said second frame providing a second position for said through bore, said first and second positions accommodating different door thicknesses wherein the edge bore is centered in the door thickness.  
   
   
       5 . A method for securing doors in wood and metal door frames for shipping said doors and door frames to a building site for building installation, said doors secured by hinges at one side edge to the door frame and said doors and door frames prepped at an opposite side edge for latch mechanism which is to be installed at the building site; said method comprising: 
 inserting a door plug through a prepped face bore and edge bore in said door and extended from the edge bore through a striker prep opening in the door frame and defining thereby an extended end portion of said door plug;    for wood frames, said striker prep opening mated to the extended end portion of said door plug and securing said door plug to the frame and as secured preventing lateral movement of said door plug and door relative to the frame; and    for metal frames having striking prep openings oversized relative to said extended end portion of said door plug, providing a bushing having a through bore mated to the extended end portion and a protrusion providing an edge portion surrounding said through bore and mated to said striker prep opening;    inserting said protrusion into said striker prep opening and inserting said door plug extension into said through bore to secure said door against lateral movement relative to said frame and applying a fastener to the end extension of said door plug to thereby secure said door plug to said metal frame.
