Abstract: An integral multi-functional apparatus is used with building trusses which provides structural integrity in the horizontal and vertical dimensions. The apparatus also serves to permit ventilation and maintain insulation in a desired position. Each apparatus includes a face plate having a plurality of air passages, a back plate having a lip, opposing stud straps for vertical interconnection of truss chords with the frame, and opposing truss chord flanges for horizontal interconnection of the truss chords. A top truss chord web is joined to each truss chord flange for securement to the top of the truss chord. A top plate tab is also joined to each truss chord flange for attachment to the top plate of the frame.
