Cassette Roller Blind UNI (Cassette – UNI 19 mm)
The product’s maximum size depends on two factors: the control type (chain or spring) and the fabric weight and thickness. Lighter fabrics (below 230 g/m²) can be produced in larger dimensions, while heavier or blackout fabrics (above 230 g/m²) have smaller maximum dimensions to ensure smooth operation and long durability.
What does this mean in practice?
- Chain control generally allows a greater drop than spring mechanism.
- Lighter fabric → larger possible width and height.
- Heavier fabric → reduced maximum sizes due to roll diameter and load.
Example values – fabric < 230 g/m²
| Control | Min width | Max width | Max drop | Max area |
|---|---|---|---|---|
| Chain (option 1,2,3) | 30 cm | 150 cm | 220 cm | 2.4 m² |
| Spring (option 4) ø25 | 35 cm | 150 cm | 180 cm | 1.8 m² |
Example values – fabric > 230 g/m²
| Control | Min width | Max width | Max drop | Max area |
|---|---|---|---|---|
| Chain (option 1,2,3) | 30 cm | 120 cm | 190 cm | 2.1 m² |
| Spring (option 4) ø25 | 35 cm | 120 cm | 150 cm | 1.6 m² |
The figures above are indicative for the UNI 19 mm system. Larger sizes may be possible depending on the fabric and installation type, but require technical verification. Please contact us for advice on larger dimensions or specific fabric options.
