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. After the door assembly is installed, the first portion is removed from the door. The second portion remains on the strike jamb.
