ABSTRACT:
A plurality of parallel constructed members that have means for securing the two parallel members together along an axis parallel to the longitudinal axis of the members to lend structural support of the members relative to each other. This allows the structurally secured members to have structures having high strength to weight ratios and requiring minimum volume for the securing structure.
