Abstract: A universally adjustable bracket structure for supporting a television receiver cabinet to accommodate viewing. The loop portion of a generally U-shaped bracket is provided with a swivel mount for a television receiver cabinet. A cube-shaped block is releasably retained between the leg portions of the bracket, and an adjustable clamp is mounted on the block for clamping of the bracket on ledge support structure that extends horizontally or vertically. Appropriate disposition of the clamp, in accommodation of viewing, is afforded by adjustability of the cube relative to the U-shaped bracket, or of portions of the clamp relative to the block.
