Abstract: A shutter panel apparatus having a shutter frame with a pair of stiles, spaced apart and generally parallel to one another, and a bottom rail and a top rail, each connected to the stiles. A plurality of generally parallel louvers are rotatably connected to the shutter frame such that each louver is rotatable along a longitudinal axis. The top rail is non-linear in shape and has a back face and a front face, the back face of the top rail having a recess therein for receiving the first end of an upper louver, the first end of the upper louver rotatably connected to the top rail. The invention has several embodiments and allows for the rotation of an upper louver or louvers where the top rail is arched, semi-circular or elliptical. The invention further allows for rotation of an upper louver or louvers where the shutter frame is circular, hexagonal or the like, and where the top rail is angled with respect to the stiles.
