Guide rails for each sliding door and gate system must be mounted horizontally to prevent the door from unintended moving.

Heavy passage doors and gates are always mounted on the wall of the building, and their purpose is to cover the opening in the wall. By measuring carefully the opening, find the smallest rectangle that will cover the contour of the opening. The height and width of this rectangle will define the minimum size of the door. After determining the height and width, you need to define – based on the assembly instructions – other values, such as the length of the guide rail and the size of the door/gate wing.
