A bracket assembly includes an angle bracket which may be formed from a single-piece metal blank which can be shaped and bent to define in its load-bearing form a substantially triangular bracket having a horizontal leg and a diagonal leg as well as a vertical support which may be similar to the horizontal leg. Each of the legs have a pair of upstanding sidewalls which extend normally from an associated base to form a substantially U-shaped cross-section. The diagonal and horizontal legs are contiguous and are connected by a first bendable section to define a first acute corner, the vertical and diagonal legs are contiguous and are connected by a second bendable section to define a second acute corner and the vertical and horizontal legs are interconnected to define a third corner. The bracket assembly also includes a lower bracket arm captured at the second corner by at least one surface irregularity and a bolt captured at the first corner by at least one surface irregularity as the angle bracket is formed into its load-bearing shape. In one embodiment of the present invention, the bracket assembly further includes an extension assembly attached to the angle bracket at the first acute corner. The extension assembly is pivotally mounted on the angle bracket so as to increase the overall size of the surface on which a horizontal plank can be placed to create a scaffold.
