Abstract: A shutter assembly comprising a plurality of vertically spaced, horizontally extending louvers rotating between a pair of opposed vertical side rails causing them to control the light and air passing through the shutter from a maximum, when in the open position, to a minimum, when in the closed position. All parts are made primarily of wood. The pivoting movement is in response to the operation of a tilt rod containing "U" shaped, malleable metal staples coupled with similar staples inserted into each louver, and of a type normally used. Both sets of staples are crimped as close as possible to their junction points so that they become two interlocking eyelets. When the shutter is in the upright position and the louvers are closed, the surface of the louver facing the observer is considered the front surface and the margin containing the staple, the upper margin. From a position about half way down the upper margin there is a slightly angled slope which intersects the rear surface of the louver.
