2.Check if the hinge groove matches the height, width, and thickness of the hinge.
3.It is necessary to check whether the hinge matches with other connecting screws and fasteners.
4.Whether the hinge connection method is the same as the material of the frame and fan, such as the hinge used for the steel frame wooden door, the side connected with the steel frame is welded, and the side connected with the wooden door leaf is fixed with wood screws.
5.In the case that the two pages of the hinge are asymmetrical, it should be distinguished which one should be connected to the fan, and which one should be connected to the door and window frame. The side connected to the three sections of the shaft should be fixed to the frame, and the side connected to the two sections of the shaft should be fixed to the frame.
6.When installing, ensure that the shafts of the hinges on the same leaf are on the same vertical line to prevent the doors and windows from springing up, so that the glass door hinges can be installed.
