Two spaced apart elongated anchor straps are adjustably attached to opposite ones of the wall portions and are adapted to be secured by nails or like connectors to opposite sides of the top portion of the roof truss and further wherein each anchor strap includes a lower length disposed and adapted to be embedded in wet concrete initially defining the tie beam of the building on which the channel length and truss rests.
