ABSTRACT:
A molding connector is described for interconnecting molding ends together to form a frame. The molding connector comprises a male and a female connector formed respectively in a beveled molding end of two moldings to be interconnected. The male connector has a connecting rib formed in the molded end provided with a securing head having an angulated guide edge. The female connector has a rib engaging slot disposed in the beveled molding end with the slot having an enlarged securing cavity for receiving the securing head of the connecting rib in guiding engagement. The connecting rib is positionable into the slot with the head received in the securing cavity, and the angulated edge as well as the securing cavity permitting the beveled ends of the two moldings to be progressively aligned with one another, as the rib is pushed into the slot. The rib and cavity provide a clamping force to interconnect the beveled ends in facial abutting relationship. A flange is also formed in an exterior surface of one of the mated moldings to overlap a joint formed between the interconnected bevel ends and provides an offset joint having a back wall.
