Abstract
An apparatus for holding a substrate includes a shelf capable of holding the substrate; a body which encloses the shelf, the body having an open side; and an outer door frame pivotally coupled to the body and defining an opening. The apparatus also includes an inner door which fits into the opening. The body's open side is substantially covered by the inner door and by the outer door frame when the inner door and outer door frame are in closed positions. The apparatus can include a double hinge for pivotally coupling the outer door frame to the body. It can also include a bolt that is movably attached to the inner door, so that the inner door has a locked position in which the bolt extends into the frame and an unlocked position in which the bolt retracts from the frame.
