Roller Blinds RT-32 · RT-40 · RT-45 – Size limitations depending on fabric and control type
Our free-hanging roller blinds in the RT series are available in several tube diameters (32, 40 and 45 mm).
The maximum allowed dimensions depend on two main factors:
the control type (chain, motor or crank) and the fabric weight and thickness.
Lighter fabrics (below 230 g/m²) allow larger blinds, while heavier or blackout fabrics
(above 230 g/m²) require smaller maximum sizes to ensure smooth operation and long product lifetime.
