Openable insert for door and method of installation

A door with an openable insert mounted therein, the door comprising in combination:

• a substantially planar door element including an inside surface opposite an outside surface, said inside surface spaced from said outside surface by a door thickness, said door including at least one hinge on a first vertical edge thereof adapted to pivotably mount said door to an adjacent support;
• said door including a hole extending from said inside surface to said outside surface, said hole partially defined by a pair of substantially vertical sides located parallel and opposite each other;
• said insert located within said hole, said insert including a frame assembly, a mounting plate and an inner door;
• said frame assembly sized to fit adjacent said hole and overlap at least portions of said vertical sides of said hole adjacent said outer surface of said door;
• said mounting plate sized to fit adjacent said hole and overlap at least portions of said vertical sides of said hole adjacent said inside surface of said door;
• said mounting plate removably attachable to said frame assembly through a plurality of elongate fasteners passing through holes in said mounting plate and into holes in said frame assembly;
• at least portions of said door sandwiched between said mounting plate and said frame assembly with said fasteners applying a force to clamp said mounting plate and said frame assembly to said door therebetween;
• said inner door pivotably mounted to said mounting plate;
• wherein said fasteners and said holes in said mounting plate for passage of said elongate fasteners are covered by portions of said inner door when said inner door is pivoted to a closed position, said elongate fasteners extending substantially perpendicular to a major planar face of each of said door and said frame assembly.
