The door has a hinged system, meaning the door and panels are not on the same straight line. The door operates from the rear, closing over the panels on the right and left.

For standard doors, the door opening is 64 cm, the door panel width is 70 cm, and the height is 181 cm. The door closes 3 cm above the right and left panels. This excess due to the door panel causes the total length to be approximately 6% higher. For doors with a panel height of 183 cm + base + header, the finished door height varies between 194 cm and 199 cm. The minimum wall height must be 205 cm.

Doors with a gap between two walls of 92 cm - 94 cm do not require feet. For gaps greater than 94 cm, a total of two feet are used, one on each of the right and left wall panels. These feet are mounted to the panels on the right and left of the door.
