ABSTRACT:
A corner construction having high strength and resistance to torsional forces for use with hollow elongate tubing members. A first longitudinal member extruded from aluminum includes a pair of parallel planar walls connected by a planar web along one edge and a stepped web along the other edge. A second similar member is provided having a spacing of its walls for slidably receiving the first member therebetween. The stepped web of the second member at a terminal end thereof is cut away to form steps complementary to the stepped web of the first member. A terminal end of the first member is inserted between the walls of the second member to abut its planar web and to cause the stepped web to abut the cut-away steps of the second member. Fastening means is provided for maintaining the first member in its abutting relation with the second member.
