TRH-A series grilles have a simple design which makes them useful for
incorporation in all styles of architecture.
Their special features make them ideal for placing in doorways and interior
walls.
The “V” shaped profile of the blades allows the passage of air but prevents
light from entering, and at the same time reduces the sound pressure level.
