Abstract Method For Installing Elevator Hall Doors A method is disclosed for installing a hall door on a floor when the elevator rails or car are not installed. A template is placed at one terminal or end of the elevator shaft and is used to locate the position of a temporary bracket containing three holes which are spaced apart to correspond with three marks along the sill of the elevator door assembly. The holes are on a common line and are at a preestablished distance from the wall of the shaft. Once this bracket is installed in the shaft, a plumb line is extended from each of the holes to another bracket below. The plumb lines hang next to the floor on which a hall door is to be installed. This other bracket is positioned so that the plumb line passes through the center of a corresponding hole in the bracket. A door alignment tool is positioned between the sill of the door and each of the plumb lines, and the thickness of the tool, which defines the setback distance between the door and the plumb lines, establishes the setback distance between the door and the edge of the shaft. The tool is used in this manner with each plumb line and on each floor for each door thereon in an installation process that provides for correct orientation of the door sill relative to the lines and thereby also the correct orientation relative to the template, which is keyed to location of the elevator rails or car, which are subsequently installed. After the door is plumbed to the floor, it is permanently attached to the floor and walls of the building.
