ABSTRACT:
A frame corner joining apparatus for joining two metal picture frame members at a predetermined angle to form a frame corner. The joining apparatus includes first and second legs disposed at the predetermined angle relative to each other, each leg receivable in a corresponding frame member channel. Each leg includes a fillet surface and a sloping surface, having a slot and a wedge piece with tab received in the slot. The wedge piece may be in two positions: an unlocked position in which the wedge piece is at the lowest point on the sloping surface, and a locked or raise position in which the top side of the wedge piece engages a surface of the picture frame. The wedge piece may be adjusted manually with needle nose pliers or automatically with a pneumatic device until the fillet surface of the frame corner joining apparatus tightly abuts the back lip edge of the picture frame member.
