Abstract
A pair of frame members have ends beveled at an angle of 45.degree. and mated with one another to provide a miter joint. The frame members have perpendicularly arranged plates each having an opening adjacent its one end to provide a separate end portion. A corner angle is mounted on the plates and has a pair of legs each having a projection of a V-shaped cross-section received in one of the openings. The V-shaped projections jointly provide a pair of substantially parallel members for clamping the separate end portions, the parallel members being fastened together by a screw passing therethrough. As the screw is tightened, the clamping members are moved closer to fasten the separate end portions securely together and to press the angle legs against the plates of the frame members.
