The extremely stable Heavy-Duty system is designed specifically for heavy or oversized door Leafs with large opening widths and high continuous loads.

As a further benefit, the system can also be used as a multifunctional door – including integration in building security and automation systems, e.g. as a panic door in office and public buildings, hospitals or schools. Together with its narrow face widths, diverse design options and increased burglar resistance and sound reduction, the system makes flexible door solutions possible for the starkly differing requirements of commercial construction.
