Decomatic Slope is a heavy-duty vertical head rail system capable of rotating and traversing at widths up to 240" for commercial and residential applications. The Decomatic Slope head rail can operate on angles up to 64 degrees and to 55 degrees before you need to cut the corner of the vane. Our slope head rail offers complete functionality (tilt & traverse) as well as a built-in cord lock to lock the stacked vanes to the highest point.
