ABSTRACT:
A frame assembly is formed of two molded sub-assemblies, each sub-assembly being identical to the other. Each sub-assembly has a perimeter wall having an inner surface facing an opening and an outer surface to face a edge of an aperture in a partition. A first edge of the wall confronts a surface of the window while a flange projects outward from the outer surface of the perimeter wall. A plurality of joining elements are fixed to and project normally from the flange. Each joining element includes an alignment element and a locking surface to engage a similar surface on an aligned joining element of a confronting sub-assembly. The joining elements are arranged in a pattern that permits any two sub-assemblies made in the same mold to be permanently snapped together without the use of any separate fasteners.
