ABSTRACT:
An louver rotation mechanism for use in rotating a louvered shutter having louvers rotationally engaged with a frame. The device features one or a plurality of gear modules which are positionable to a fixed location on one or a plurality of rack bars. The gear modules may be spaced on the rack bars to any number of positions wherein they will engage with louver gears from an array of louvers engaged with the frame. A high degree of customization is provided by allowing the use of the rack bars with any number of different sized louvers at different spacings in a frame by simply adjusting the positions of the rack modules for operative engagement with the louver gears.
