Abstract: A support bracket for a sawhorse, by which the legs are connected to the spine rail of the sawhorse, and provide full collapsibility of the legs. In a preferred embodiment, the bracket has an intermediate panel and side panels, in an overall generally U-shape, with the intermediate panel disposed generally vertically, and transversely of the axis of the spine rail; and the side panels, which extend from the intermediate panel, pivotally carry the sawhorse legs. Co-operative latch components of the side panels and the legs latchingly hold the legs in optionally an extended position or in a retracted position generally juxtaposed along the spine rail, providing that the sawhorse may be easily changed from a conventional erect condition to a collapsed condition in which the entire assembly occupies scarcely any more space than the spine rail of the sawhorse; and the latch has a special feature which permits that fullness of leg-collapse regardless of which of the legs are first moved to collapsed position.
