Abstract: An air turning vane and rail assembly for use in heating, ventilating and air conditioning ducts is provided. The rail is formed with tabs that are partially punched from the sheet metal rail and bent to a position perpendicular to the rail. The tabs are further bent to generally approximate the arcuate shape of the vanes to be received by the rail. The tabs extend the full width of the vanes that are positioned on them. Either single walled or double walled turning vanes are positioned on the tabs and the tabs and the vanes are crimped together to retain the vanes on the tabs. Because the tabs extend the full width of the vanes, the vanes are automatically positioned so that they are parallel to each other and so that their vertical center lines are aligned with each other.
