A variable lot size load port assembly is described having a tool interface, a port door, a latch key, an advance plate, and an elevator. The tool interface extends generally in a vertical dimension and has an aperture. The port door has a closed position wherein the port door at least partially occludes the aperture. The latch key extends from the port door and is configured to mate with a latch key receptacle of a door of a front opening unified pod (FOUP). The advance plate is configured to support a front opening unified pod (FOUP) and translate between a retracted position and an advanced position. The elevator raises and lowers the advance plate to bring the latch key receptacle of the door of the FOUP into alignment with the latch key of the port door.
