Three different mounting methods for the hinge:
Full cover (straight bend): The door panels all cover the side panels of the cabinet with a gap between them so that the door can be opened smoothly.
Half cover (medium bend): In this case, the two doors share a side panel. There is a minimum gap required between them. The coverage distance of each door is correspondingly reduced, requiring the use of a hinged hinge.
Built-in (big bend): In this case, the door is located in the cabinet, next to the side panel of the cabinet. It also requires a gap so that the door can be opened smoothly. A hinge with a very curved hinge is required.
