A vane rail has a plurality of tabs, in pairs, partially severed therefrom, to engage air deflection vanes in sandwiched relation therebetween. Fasteners may secure the connection between the sandwiching tabs and the vanes. When vanes and a pair of rails are used together in engagement with the vanes, an assembly is provided for disposition in an air duct for intercepting air flow in a duct and diverting it to a different direction.
