The new small pulley makes it easy to butt two motorized drapery tracks together for track widths exceeding 36ft. or draperies exceeding 132lbs. By using this pulley, in combination with the new RippleFold® Butt Arm (1782319), you can now create the appearance of a center open motorized drapery by using two one way tracks butted together. The new small pulley can also be combined with Somfy's One Way Pinch Pleat/RippleFold® Overlap Arm #1782320.
