Abstract
A peg which forms part of a frame for setting up the lines around excavations preparatory to erection of buildings or the like has a post the lower end of which is provided with a laterally extending plate welded to the web of a U-shaped leg whose flanges have aligned openings for the shank or shanks of one or more nails which are driven into the ground at an acute angle to the axis of the post. A second U-shaped leg is welded to the lower end of an inclined brace which is adjustably coupled to an intermediate portion of the post. A third U-shaped leg can be connected to the outer ends of two reinforcing members whose inner ends are integral with the post. Additional openings for the shanks of nails can be provided in the webs of the legs.
