ABSTRACT:
A one-piece frame corner joining apparatus for joining two picture frame members at a predetermined angle to form a frame corner. The frame members are preferably standard aluminum frames having a longitudinal channel for receiving corner hardware. 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 top side and a bottom side, a bore, a screw received in the bore, and a tab portion connected to the bottom side of the leg. The tab portion is formed of a strip of the leg that is bent back over the bore and spaced apart from the leg such that the screw, when tightened, deflects the tab downward to frictionally engage the leg with the corresponding frame member channel.
