Abstract
Abstract A wooden construction is disclosed comprising a bracket supported by a single screw in a grooved vertical standard. The groove prevents the bracket from twisting on the screw. Screw holes are provided at intervals in the bottom of the groove so that the bracket may be shifted up or down on the standard. Portions of the groove not occupied by the bracket are filled by a filler strip. The back side of the standard has a central tongue to fit between the edges of two adjacent wall panels whereby the standard also serves as a molding strip to cover the joint between the panels.
