Corner exterior blinds in a coupled design are the best solution for corner portals of houses and buildings. Among other things, this product solves the problem of shading corner windows without a guide rail remaining in the centre and disturbing the overall view from the interior to the outside after the blind is pulled up. The slats are connected by a stainless-steel ball chain in a plastic guide. The lower slat profiles are connected with a metal angle piece inserted in a plastic corner. The corner blind can be used for both inner and outer corners, but always only for a 90° angle!
