ABSTRACT:
A method and apparatus for constructing an access door assembly for providing entry to a crawl space or other storage area within a building is disclosed. The present access door assembly is constructed from a single blank of material by accurately cutting a door panel from the blank and simultaneously creating a peripheral frame wherein the door panel is mounted. The kerf resulting from the cutting process provides a predetermined clearance between the door panel and peripheral frame to permit installation of hinges and latching hardware to ensure proper functioning of the completed door assembly. The method of the present invention significantly reduces the labor costs involved in installing an access door by the conventional process, which requires sizing of a door to a preexisting opening, mortising hinges, and mitering and fitting a finished molding about the access door.
