  • AAH804 hinges are produced in Italy and tested according to the norm EN1935. In some cases, the use of a fourth hinge may be decisive for the load capacity, especially in case of large widths (>1000 mm) or heights (>2700 mm), on which ASSA ABLOY suggests to install the fourth hinge in the upper part, 250 mm from the first one.

    ASSA ABLOY suggests to always install a third or fourth hinge in the upper part of the door in the presence of door closers. More specifically, as per the European reference standard EN1935, when calculating the load capacity:

    • With door closers without brake on opening, consider +20% compared to the real mass of the door.
    • With door closers with opening brake (backcheck) consider +75% compared to the real mass of the door.
    • In case of door height >3000 mm or special uses, please contact our technical office in advance.
