The main body has front, rear, top and bottom portions. The pivoting slat is disposed adjacent to the front portion. The pivoting slat has a leading edge, and a top and bottom sides. Each of the beam members has a front end, a rear end, and a pivot point. The front end of the first beam member is coupled to the top side of the pivoting slat. The front end of the second beam member is coupled to the bottom side of the pivoting slat. The first beam member is rotatably attached to the top portion of the main body at the pivot point. The second beam member is rotatably attached to the bottom portion of the main body at the pivot point.
