Counter flanges

Counter flanges duplicate the hole patterns of the fan flanges and are produced in different kinds of materials depending on the intended use. Flanges in sheet steel are for welding on to existing ducts to enable fan attachment, while flanges in galvanised material are for installation as backing on wall-like surfaces.
