Abstract: A new and useful anchor for use in the installation of a composite building panel. The anchor comprises a vertically upstanding wall mounting face and a spacer extending normal to the wall mounting face. Spaced outwardly from the wall mounting face by the spacer there is provided a first longitudinally extending flange-receiving groove opening in a first vertical direction. Adjacently deposed to the first flange-receiving groove with a common middle wall there is provided a second longitudinally extending flange-receiving groove opening in an opposite vertical direction. Fasteners mount the anchor means to the wall.
