One of the distinguishing features of this awning is the possibility of using the arms with or without spring, offering options for controlling the tension of the fabric and flexibility in opening and closing the awning, adapting to specific needs. Ideal for partially closing window lights or creating shaded areas, the T400 awning offers an excellent solution for regulating the amount of natural light that enters, while providing a decorative and elegant touch. The presence of the crossbar adds further versatility, allowing you to modulate the light and view as needed.
