The UCS Duoplissee cassette roller blind from Horrex consists of a system in which it is possible to change the design (frame cladding and profile elements) to other colours, depending on the individual design. The standard colour is beige (RAL 9001). Two roller blinds are housed in flat cassettes with practical roller blind rear ventilation. They are infinitely adjustable and are opened in opposite directions and stowed in the aluminium strip with a central lock. The fastening is done with 1 screw per corner. No visible screws are visible and the roller blind is completely pre-assembled.
