The arched center section extends outwardly above planes defined by the wing sections, and the wings and arched center section define an interior surface which is placed adjacent the wallboard and an exterior surface which is placed opposite the wallboard. A reinforcing member is disposed adjacent the interior surface of the arched center section and attached thereto to provide rigidity to the arched center section. |
