Una buena solución de adaptación.

Tenia un tubo de ventilación sacado por la ventana y pillado con esta. Y se caía cada dos por tres y quedaba muy feo visto desde fuera. Con este adaptador lo pillas con la ventana y lo pegas con un poco de cinta americana y es mucho mas discreto y el tubo no se va a mover jamas.
