ABSTRACT:
An improved shutter construction is provided with a plurality of louvers supported by relatively low friction two-piece bushing assemblies for pivoting movement with respect to a shutter frame in response to operation of a louver tilt rod. The bushing assemblies permit movement of the louvers together substantially without binding between an open position to admit light and air and a closed position wherein ribs and grooves formed on the louvers interlock with one another such that the louvers substantially block passage of light and air.
