The MLL sun protection system VS-V-300-SD from MLL Hamburg is sun protection made of large elliptical aluminium slats. The system is a vertical, facade-parallel sun protection with vertically-arranged slats of type sonal D-300. The slats are connected by means of the star cap directly or with lesene profile RL-120-40 to the on-site substructure. The slat tilt can be adjusted via the star cap. Available tilt angles are 0°, 15°, 30° or 45°. Other tilt angles can be implemented, however.
