The FLAT BESTA system is designed for roller-blinds to be mounted without any adaptations on the door or window sash with the glazing beads higher than 20 mm. Using the space between the surface of the window sash and the surface of the glass, the system is extremely flat, so it possible to open fully the window or door.
