    Abstract: A tie down assembly adapted to be installed within a structure includes a cup and a crossbar that is fastened removably to the cup by a plurality of fasteners. The cup includes a recess forming an interior surface, and a plurality of seats extending from the interior surface. The crossbar includes a central portion and a plurality of elongated members extending therefrom. Each of the members includes a head that engages a corresponding one of the seats of the cup and is secured to the seat by one of the fasteners. The central portion of the crossbar may include a central aperture that receives one of the fasteners for an additional attachment point to the cup. The crossbar is adapted to receive tie down hooks, connectors, and the like. When the crossbar requires repair or replacement, it may be removed from the cup by unfastening the fasteners without the need to remove the cup from the structure.
