Abstract: An air directional louver device, which incorporates one or more multi-grooved ratchet style notches to cooperate with corresponding mating fixed pointer to mesh together. Once the rotating ratchet grooves on the louver's axles and one or more fixed knife-edge pointer are meshed, the louver can be held better in the last desired air direction set position than without the ratchet and pointer. The rotating ratchet will help prevent also vibration and/or the forced air to the louver or to the fixed knife-edge pointer area from moving the louver frame to another undesirable position. The fixed knife edge pointer, in another embodiment, will be rounded at its point for smoother operation and applied into the louver's corresponding holding area. Further change in the friction to change the louver position from one notch to another is attained by rounding the point and deepening the notches if desired.
