The vertical-dimming systems can darken rooms up to 100%. You can choose an execution as left or right roller and are available with a dimming mechanism made from textile, Soltis- or fiberglass fabric. The beveled inspection cover of the box is visually smaller. Optionally, a rear ventilation profile can be used behind the guide rails or on the box. This consists of a ventilation strip with a dimension of 28 x 9.5 mm, made of extruded aluminum, powder-coated black mat in RAL 9005.
