The mount is the key part of the door that keeps the door running.
When the chain engages with the mount, it triggers the movement of the door panel. As the mount is driven forward by the chain, it pushes the door panel along its designated path. This mechanism ensures that the door panel is securely guided as it opens and closes, providing reliable and efficient operation. The seamless interaction between the chain, mount, and door panel ensures smooth motion and consistent performance, reducing wear and tear on the components and extending the lifespan of the door system. This precise engineering allows for controlled and stable operation, enhancing both the safety and functionality of the door.
