"Deco" Louvering. This is a 3" replica louver design of an "old time" louver that was used on hot rods many years ago. As far as I know we are the only ones offering this louver which we call the "Deco" louver. If you want something different along the art deco line, this is it at $4.00 each plus set up. In total we have 5 styles of louvers to chose from so be sure to view all of them.
