Abstract: A one-piece, unitary installation aid is provided for holding a door in place relative to a door frame in a pre-hung door assembly during transportation and installation of the door assembly in a building. The installation aid includes a wall having a inner surface and an outer surface, a door clip extending from the wall inner surface and a jamb clip extending from the wall outer surface. The door clip is sized to fit over the door, and the jamb clip is sized to fit over the jamb. The door clip and jamb clip interact with the door and the jamb, respectively, to positively hold the door closed in the frame and to prevent pivoting of the door in the frame.

Abstract: An installation aid is provided for maintaining a door closed in a door frame during transportation and installation of a door assembly in a building. The installation aid can be used with both interior and exterior doors. The installation aid is a two piece assembly including a first portion which is received in the door and a second portion which is received on the back side of the strike jamb of the door assembly. The first portion has a head, a stem extending from the head, and a threaded shaft at an end of the stem. The second portion includes a washer and an internally threaded boss extending from the washer. The first portion shaft and second portion boss threadedly engage each other to hold the two pieces together, and hence to hold the door in position in the door frame during shipping and installation of the door.

Abstract: An installation aid is provided for maintaining a door closed and square relative to a door frame in which the door is hung during installation of a door assembly in a doorway. The installation aid includes a first portion and a second portion which are connected together by a screw when the installation aid is installed in the door assembly. The first portion includes a head which is received in a door knob hole of the door and a post which extends through a door knob bolt hole of the door. The second portion includes a base which is secured to an outer surface of the strike jamb and a post which extends through a lock hole of the strike jamb. The posts of the first and second portions are telescopically interconnected and include screw holes which are axially aligned when the door is closed. The screw hole of the first portion is off-set from a vertical axis of the first portion so that the screw hole will be closer, for example, to the front surface of the door than to the back surface of the door.
