Alouette Tilt Bar Systems 

Of the three operating systems for Alouette Light Louvers, two use a tilt bar to rotate the louvers.  With the Bar-Tab System (BTS) louvers are rotated for light control and privacy using a tilt bar at the side of the louvers. The louvers are raised and lowered using a lift tab which is contained within the tilt bar. With the Bar-Cord System (BCS) louvers are also rotated using a tilt bar but they are raised and lowered using a lift cord. 

The Alouette tilt bar systems look great, operate easily, eliminate cords and provide greater safety.  All three systems, when properly installed and adjusted allow very good closure of Alouette's elliptical louvers.  If an Alouette tilt-bar system does not close tightly in both the up and down positions, this simple adjustment will usually fix it.

Rather than moving the pivot bracket, This simple adjustment should do the trick.  Also, there may be occasions in which an obstruction requires you to be at a different height. this adjustment will allow you to compensate for that.

	Use a nickel to rotate the cam on the pivot arm connector. Rotate it about one-quarter turn so that the narrow part of the cam points upward.
	With the headrail and louvers perfectly horizontal, slide the pivot arm connector up or down the tilt bar until the pivot arm is also horizontal. Rotate the cam one-quarter turn to lock the pivot arm connector in position.  Check operation and re-adjust if necessary.

Best of all—when you're done you can put the nickel back in your pocket!
