1. A stanchion assembly for retaining cargo in a hold from lateral motion, the hold having a deck grid fitting assembly and a ceiling grid fitting assembly, the stanchion assembly comprising:
an elongated beam extending in a longitudinal direction from a lower end to an upper end, the beam comprising a box cross section comprising two parallel webs extending longitudinally and two parallel flanges extending longitudinally and connecting the two parallel webs, the beam further comprising an extrusion, the extrusion comprised of an aluminum or aluminum alloy;
wherein ends of the webs of the beam overhang the flanges, whereby gripping or attachment edges are provided;
a lower end cap on the lower end and an upper end cap on the upper end, the lower end cap having a fitting thereon to mate with a corresponding fitting on a grid assembly on a deck, the upper end cap having a fitting thereon to mate with a corresponding fitting on a grid assembly on a ceiling;
a spring assembly disposed within the elongated box beam and configured to bias one of the lower end cap or the upper end cap longitudinally outwardly of the beam, wherein the spring assembly retains the beam in a vertical position with the lower end cap within the corresponding fitting on the grid assembly on the deck and the upper end cap within the corresponding fitting on the grid assembly on the ceiling;
the stanchion assembly having a weight no greater than 67 pounds;
the stanchion assembly having a length L in the longitudinal direction from the lower end cap to the upper end cap when the spring assembly is uncompressed; and
the beam having a stiffness capable of resisting a design load applied to one of the webs normal to the longitudinal direction with a deflection no greater than L/90.
