Hermetic awning with fabric contained sideways in zip guide and with an automatic lock/unlock system. When the terminal bar goes down, it moves into action a system that wedges the terminal bar into the foot and let fabric strain. To open the awning you release the fabric and the system unlocks. Side guides are inspectionable. Fabric remains in tension into the guides thanks to springs’ push. The upper cassette profile is opening so that fabric can be changed without disassembling the entire awning and moreover it allows placement of internal curtains. It is a self-supporting system or it can be pre-assembled and then installed.
