Multiple panels stack up accordion-style to the interior with zero wasted space in your opening. Perfect for spaces where interior tracks would distract from your design or cover up lighting, sprinklers, or HVAC systems.  This system is constructed from aluminum and is suitable for commercial, retail, and residential applications. 
 
The Sovereign system is balanced by the use of torsion springs connected to a rotating shaft.  The ends are attached to cable drums that lift/lower the curtain.  The Sovereign creates a flexible space and an efficient space management solution, without the typical pitfalls of a garage door, such as tracks, impeding your space.
