Modular Design System
Wouldn’t it be nice to have a single system that can accept interchangeable circular covers or grates with the same frame? The Icon-Septech MDS (Modular Design System) delivers exactly that.
Once your frame is installed, it is easy to interchange from solid top covers, to concrete infilled. Or alternatively grates with high efficiency hydraulic flow characteristics back to covers. The choice and flexibility are yours with the Icon-Septech MDS system.
