Door hardware and floor strike installation tools for a portable door shelter lock

A method for precisely defining the locations of a door lock mounting bracket on a door and a corresponding floor strike in a floor and the installation of the same such that a door lock mounted in the bracket consistently and precisely engages the floor strike, said method comprises:

• (a) releasably securing a first installation tool to the door that simultaneously and mechanically aligns locations of mounting apertures in the door lock mounting bracket with a location on the floor for forming a well to receive said floor strike therein;
• (b) forming a plurality of apertures in the door, corresponding to said mounting apertures, using said first installation tool which comprises a pair of plates that couple to an outer door surface and an inner door surface, respectively, each plate comprising said plurality of apertures;
• (c) using said first installation tool to define the precise location of the well on the floor;
• (d) disengaging said first installation tool from the door;
• (e) releasably securing a second installation tool to the door using said plurality of apertures in the door, said second installation tool having a vertically-mounted drill that, when said second installation tool is releasably secured to the door, is fixedly positioned at a precise distance from the door corresponding to the location of the floor strike, said vertically-mounted drill being displaceable along a horizontal axis parallel to the door, said drill also being vertically-displaceable;
• (f) activating said drill and lowering said drill such that a drill bit drills down into the floor to form a portion of the well;
• (g) raising said drill and incrementally displacing said drill along said axis;
• (h) repeating steps (f)-(g) until the well is formed within the floor;
• and
• (i) disengaging said second installation tool.
