|---|---|
| Basic Module (M) | Typically 100 mm (standard) |
| Windowset Width/Height | Multiples of 3M (e.g., 300, 600, 900 mm, etc.) |
| Coordinating Sizes | Predefined sizes for doors/windows (e.g., 2100 mm height, 1500 mm width) |
| Height (mm) | Width (mm) |
|---|---|
| 2100 | 700, 900, 1200, 1500 |
