Techniques for a door system for sealing an opening between two chambers in a semiconductor processing system are described. The opening has at least one angled corner. The door system includes a door, actuator, and sealing member. The door is moveable in the plane and has at least one angled corner to align the door with the opening. The actuator moves the door to selectively open and close the opening. The sealing member seals the opening when the door is in a closed position. The door is sized to apply substantially uniform seal compression to the sealing member when in the closed position.
