The extending grille Briareo has an "accordion-like" structure, which makes the opening and closing processes very simple. Also thanks to an easy mechanical working principle it can be installed on any type of windows or balcony door.
One of his peculiarities is that it does not need a bottom guide rail: the look of the fitting is therefore not altereted, differences in level are avoided and the passage is free.
Briareo is available in single or double leaf and with external or walled frame, or folding opening.
Thanks to its Silver colour it is almost invisible.
