Briareo is the folding grille designed by DI.BI. to protect your house and your purchasing power.It is easy to open and close thanks to its "acordion-like" structure. It is mechanically operated and suitable for installation on any type of windows or balcony door. It is the only product of this kind that does not need a bottom guide rail: the look of the fitting is therefore not altereted. It allows an easy installation in balcony doors avoiding any difference in level and keeping the passage free. It is available in single or double leaf and with external or walled frame, or folding opening. Almost invisible thanks to its Silver colour.The name of the DIBI folding grille comes from the name of the giant Briareos, the mythological Greek character with one hundred arms.
