Review on Dumble Blades Replacement D Bore Bathroom by Charles Russell

I recognized mine but my knife (#5593) rotates CLOCKWISE instead of counterclockwise as described in the description. As stated in the description, the rotation is determined by looking down at the fan as if looking down at the RV on the roof of an RV. When I first installed the fan blade, it blew air into the RV from the outside. But my blade had enough room for me to install the fan blade upside down without hitting anything, so everything works fine. Otherwise I would have had to swap the cables as suggested in the description.
