Abstract

This product is a component that forms a door opening, such as a hinged door, and is a door frame material used in the upper frame. As shown in the reference diagram illustrating the state of use, the ceiling board is supported by the notches on the left and right edges of the bottom surface of this product, and the right side forms the same surface as the ceiling board, allowing ceiling cloth to be attached to form the ceiling surface. Furthermore, a protrusion is provided on the bottom surface downwards, which can block light leaking from the top edge of the door.
