Abstract: An attachment for a building structure comprises a securing means shaped to locate on a corner of a structure. Two arms are supported by the securing means so as to extend divergently to locate along adjacent faces of the structure to opposite sides of the corner. The arms are provided with engagement portions at their remote ends for engagement into a respective one of the adjacent faces of the structure. A single adjustment means is arranged to effect sliding of the arms along the adjacent faces towards the corner to urge the engagement portions into clamping engagement with the structure.
