ABSTRACT:
A support for a pair of generally 90.degree. relatively angulated staple guns is provided and the support defines a pair of aligned generally 90.degree. V-shaped notches for embracingly engaging an outside dry wall corner structure. The inner portions of the V-shaped notches are relieved to receive a generally V-shaped corner bead therein and the notches are spaced apart to engage the corner bead at points spaced longitudinally therealong. The staple guns are spaced apart intermediate the V-shaped notches and include abutment surfaces from which staples may be projected, the abutment surfaces of the staple guns substantially coinciding with planes lying along and extending between corresponding sides of the notches. The staple guns include actuators shiftable between active and inactive positions and the support includes an operator shiftable along a path bisecting the included angle for operating the actuators. A V-shaped corner bead is provided including a partial cylindrical apex portion of generally 270.degree. in angular extent and including tapering free longitudinal edge portions and projections extending longitudinally of and spaced transversely of the remote sides of the V-shaped corner bead.
