Abstract: An apparatus for safety during construction of a wood frame building includes a row of hanging supports for a plank walkway with an upper hanger portion extending over a top surface of a wall and a vertical leg attached to the hanger portion and depending therefrom to a horizontal arm extending outwardly from a lower end of the vertical leg to support the planks. A row of perimeter posts stands vertically at an edge of the building for supporting horizontal rails as a perimeter fence. Each post has a horizontal flange spaced from a bottom end projecting outwardly to one side with a first nailing hole for penetration of the nail into a top edge of the perimeter board and a second outer nailing hole and a series of nailing holes in the vertical post below the flange and fastened to the outer surface of the perimeter board.
