EASY KLICK-RAFF from VALETTA: the easy way to handle external venetian blinds. The pre-assembled venetian blind is simply plugged onto the EASY KLICK-RAFF guide rails with clips. Easily and quickly installed. A great advantage is also to combine the external venetian blind with a rollable insect screen, either immediately or later, because the EASY KLICK-RAFF can be upgraded with a VALETTA insect screen roller blind ERCI-HN at any time. Installation or upgrade of insects screens quickly and easily.
