Abstract
Prefabricated metal truss units have depending set wedges and lateral notches to rapidly center them and snap them into predetermined positions over underlying substructure made up of prefabricated metal wall panels having U-shaped channel truss locks along their upper surfaces. Diagonal members centrally pivoted to the king posts of prefabricated roof truss units have angularly oriented plumb lock elements that interconnect with king posts of adjacent units to quickly establish vertical plumbing. The tail ends of top chords are provided with soffit framework for rapid soffit plate and fascia attachment. The upper surfaces of top chords are marked to locate the first run of roof sheathing.
