Modular threshold assembly

A door frame assembly having a pair of jambs coupling a head at a jamb first end and to a modular threshold assembly at jamb second end, a stop coupled to at least one of the jambs and a door slab coupled to the one of the jambs, the modular threshold assembly comprising:

• a frame having a frame first wall and a frame second wall coupled proximate to or at opposing ends of a base;
• the frame first wall having a first end being distal from the base and the frame second wall having a first end being distal from the base;
• a cover plate detachably attached to the frame at the first end of the frame first wall and the first end of the frame second wall, the cover plate having a downward slope from the frame first wall to the frame second wall;
• and
• an elongate body detachably attached to the frame and being proximate to the frame first wall, the elongate body being adapted for positioning under the door slab,
• wherein the elongate body has an elongate body first wall and an elongate body second wall, the elongate body second wall positioned between the frame first wall and the elongate body first wall;
• a first surface extending from the elongate body first wall to the elongate body second wall;
• and a second surface extending from the elongate body first wall to the elongate body second wall;
• wherein the first surface is in a first plane and the second surface is in a second plane, the first plane being closer to the cover plate than second plane, and
• wherein the frame first wall has a projection extending towards the elongate body second wall, the elongate body second wall having a receptacle formed on a surface of the elongate body second wall facing the frame first wall, and the receptacle adapted for receiving the projection to detachably attach the elongate body to the frame.
