    Abstract: A bracket for fixing a prefabricated window to roof boards or sheathing in an inclined roof is already secured to the window main frame during the factory assembling of the window. The presecuring of the bracket is effected by a screw inserted through a hole in a positioning member which through a connecting portion consisting of a bridge and a rodlike member is integrally connected with one side edge of a first leg of the bracket. The first leg continues at its lower side into a second leg at right angle to the first leg. Before packaging the window for transportation the first and second legs are swung into abutment on the main frame by turning around the connecting portion. When the window is to be installed in the roof the first and second legs are swung through an angle of 180 DEG until the first leg abuts against the positioning member. In this position mounting screws are through the overlapping holes screwed into the main frame. Then the window is secured to the roof boards by driving screws or nails through the holes in the second leg into the boards.
