Door frame material

Abstract

This product is a component that constitutes a concealed frame for door openings such as hinged doors, and is a door upper frame material used for the upper frame. As shown in the reference diagram illustrating the usage state, the notches on the left and right edges of the bottom surface of this product receive the ceiling board and form the same underside, allowing a ceiling surface to be decorated by attaching ceiling wallpaper. Furthermore, the bottom surface of this product is provided with a trim groove, and by installing it so that the trim groove is in the center of the door and then inserting the edges of the ceiling wallpaper of the left and right rooms to finish it with a "slip joint" treatment, the ceiling boundary between the left and right rooms is hidden when the door is closed, resulting in a beautiful finish. Alternatively, a trim material can be inserted to hide the edges of the ceiling wallpaper and perform a "trim" treatment.
