Abstract: The purpose of this invention is to provide a pre engineered sub-assembled metal folding roof truss in kit form, shipped in a card-board type box. The invention permits light weight roof trusses of various lengths and pitches (eg. 24?× 3/12 pitch) to be shipped to a job site in a standard pick up truck with minimum assembly of pre-assembled parts fasten to predetermined alignment holes using fasteners for quick assembly. Lifted into place by man onto walls consisting of steel, wood or block. Thus, eliminating skilled craftsmen and the use of large equipment for shipment and cranes for setting them onto the walls.
