Manual and automatic. Everything here is extremely simple: such doors can be opened and closed either by pressing one button, or manually. The first option is very similar to the blind system: you need to press only one button attached to the door panel, after which they will close or open. Although it is not so difficult to manually open the doors. As for the cost, the automation in this case does not play a big role and does not significantly cost the cost of the entire sliding door system.
