The ASSA ABLOY OH1042FI overhead sectional door is suitable for many types of buildings, with regards to both function and appearance. High flexibility makes it possible to install this door in almost every type of building. The high light admission allows working environments with maximum lighting. The door slides up under the roof when opened, allowing free space around the door opening and leaving the door opening completely free. The door is made of insulated anodized aluminium tubular profiles, filled with sandwich panels or transparent infills, see table on next page. The frames are designed with a broken cold bridge to provide minimal thermal transmittance. This reduces energy cost (in case the space is conditioned). The frame sections have integrated finger pinch protection. There are top-, bottom- and side-seals and seals between door sections. The standard track system is made of galvanized steel. The balancing system balances the door by applying a force nearly equal to the weight of the door leaf. This allows the door leaf to be moved up and down, and to stay open in any position. The balancing system (torsion spring system or weight balancing system) supports heavy forces. In case of a spring or cable break, its counterforce is lost. The door is therefore equipped with two safety devices
