A wall jack unit for erecting scaffolding is described having a series of brackets for placement at the top of a wall and connects with a wall surface-engaging pole and truss support structure with a combination user platform for supporting a wood plank between at least two of the units. Each part has adjustable features which utilize hole-engaging connections so that a series of units can be joined or formulated on a variety of building or wall structures. The unit is made of a durable steel which is resistant to weather ladened effects. |
