Flap panels feature a rear chrome-plated steel plate connected by an articulated spherical hinge to a chrome-plated steel arm that can be directly mounted to ceiling-mounted frames. These ceiling-mounted frames, also constructed from chrome-plated steel, are equipped with movable arms to which Flap panels are anchored using articulated hinges. The frames are modular and can be interconnected in a parallel line. The panels can be rotated and inclined to create planar, concave, or convex configurations, allowing for adjustments based on both aesthetic and acoustic requirements, all of which can be easily modified at any time.
