Extruded aluminium profile in V-format with a blind step of 66 mm. Applicable where burglar-resistance is required, such as in high-voltage cabinets or for visual barriers and proper water resistance. If a blind wall with high water-resistant features is required, the blind is mounted vertically upright, with which waterproofness of class A @ 1.5 m/s is achieved. Horizontally, the water resistance is class A @ 1 m/s. Blind L.066V can be combined with blind L.066, thanks to an identical appearance.
