The MLL system type 743.4S is a ventilation grille for nipping in a window frame. This means that the framework of the weather protection grille is as thick as a sheet of glass and can be mounted with the help of the window bar. Application: Large ventilation grilles for chucking in the window frame. Suitable as a substitute for glass. The slat is S-shaped, has a large surface and is used in all situations where the overall impression of the facade surface should act softer. Our MLL-weather protection systems support the ventilation of rooms and contribute to a good indoor climate. They offer protection against direct ingress of rain and the ingress of leaves and birds in exterior openings of ventilation systems. Our weather protection products are based on different needs. Thus, we offer very individual solutions. Note: Additional product information and technical drawings can be found on the following link on our website.
