Abstract
A corner connector for a pair of extrusions having hollow interiors of rectangular cross-section is formed as an L-shaped piece of sheet metal having a pair of arms extending at an angle to one another for connecting the extrusions together at the same angle. Each of the arms has opposite longitudinal edges which are located on a common edge plane, and the common edge planes of the two arms are inclined relative to one another, so that the arms can be engaged with diagonally opposite corners of the rectangular hollow interiors of the extrusions, thus avoiding wastage of the sheet metal.
