Designed using flat panels in a curved carrier, Torsion Spring Segmented metal ceilings offer point access and 100% access to the plenum from swing-down panels making this sleek ceiling ideal for commercial spaces. The key feature of this system is the engagement of the torsion spring mechanisms with the main and cross tees, allowing safe point access for sizes up to 36" x 120" and 48" x 48" in squares.
