A corner clamp joining a pair of generally orthogonal elongated members is formed by slicing a generally C-shaped frame form an aluminum alloy extrusion so that the frame includes a member spanning opening with a pressure pad defining one extremity of the opening and an opposite opening extremity face including a threaded hole and a threaded shaft passing through the threaded hole and helically movable therein toward and away from the pressure pad. The members are joined by clamping them together between the pressure pad and the end of the movable shaft. One elongated member may be an I-beam and the other a U-shaped channel with the U opening away from the I-beam. The slice is taken obliquely to the direction of elongation of the extrusion so that the pressure pad has a non-rectangular generally parallelogram shaped face. When assembled, one edge of the pressure pad face extends generally parallel and adjacent to an inner U surface.
