A bracket assembly includes an angle bracket 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 vertical, diagonal and horizontal legs. 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 vertical and diagonal legs are contiguous and are connected by a first bendable section to define a first acute corner, the diagonal and horizontal 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 further includes a lower bracket arm captured at the first corner by at least one surface irregularity and a bolt captured at the second corner by at least one surface irregularity as the angle bracket is formed into its load-bearing shape.
