Certain embodiments of the present application relate to a sliding door system. An example sliding door system includes a frame, a sliding door, and a drop seal mechanism. The sliding door is mounted in the frame for sliding movement between an open position and a closed position. The drop seal mechanism is mounted within the sliding door, and has a deployed state in which the drop seal mechanism forms a seal with the frame, and a retracted state in which the drop seal mechanism does not form a seal with the frame. The frame comprises a projection configured to drive the drop seal mechanism from the retracted state to the deployed state as the sliding door slides from the open position to the closed position.
