view of a cross piece molding 500 upper edge 122 u2033 does not include notches since the cross piece molding 500 typically spans between parallel main piece moldings 400 which are typically a set distance apart first end 506 and second end 508 are formed with coped ends to smoothly abut the decorative pattern of main piece moldings 400 the coping may follow an inverse of the decorative portion pattern that allows first end 506 and second end 508 to receive a face of the decorative portion bottom edge 136 u2033 is also at a vertical distance that is flush with other lower edges of other molding pieces in the ceiling assembly fig5 b shows a side view of a peripheral cross piece molding 520 upper edge 122 u2032 u2033 does not include notches since the cross piece molding 500 typically spans between a main piece molding 400 and a perimeter molding such as third perimeter molding 240 the peripheral cross piece molding 520 typically spans between overlaps of suspension hardware such as the joint formed when an l bar intersects with a t bar or when a cross t bar intersects with a main t bar first end 526 is formed with a butt cut end to smoothly abut a perimeter molding the butt cut end may be formed during installation of the peripheral cross piece molding 520 since the distance between main piece moldings 400 and perimeter moldings 200 220 240 or 260 may vary in addition two.
