Patent ID: 7062887

Claim:
An intersecting structural member, comprising: a first structural member, having a first predetermined height, a first predetermined width, and a first structural member base edge; a second structural member, having a second predetermined height, which is less than the first predetermined height, a second predetermined width, and a second structural member base edge; a predefined keyway formed in the first structural member and extending to the first structural member base edge, the predefined keyway having a flange engaging tab bendable about a flange bending axis and a stem engaging tab bendable about a stem bending axis wherein the flange bending axis is substantially parallel to the first structural member base edge; an ingress area formed when the flange engaging tab is bent about the flange bending axis from a first position to a second position and the stem engaging tab is bent about the stem bending axis from a first position to a second position to receive the second structural member, so that the first structural member base edge and the second structural member base edge are substantially coplanar, and having a predetermined ingress width; and an interlocking joint created when the stem engaging tab is bent about the stem bending axis from the second position to the first position thereby pinching the second structural member against the first structural member and the flange engaging tab is bent about the flange bending axis from the second position to the first position.
